Morfic, bought TKT, are you going to add more functionality? Happy to show my support but I was expecting..... Well, more.
[Nexus 10 Original Android Development] Weedalot:
I'm also getting reboots while watching video, when I use the seek aka fast forward function.

Did anyone got a solution for this? I'm on slim bean with trinity 34
[Nexus 10 Original Android Development] TheGrayHatter:
Same issue here
[Nexus 10 Original Android Development] anazei:
Happened to me yesterday as well.
[Nexus 10 Original Android Development] midgetzombiekiller:
Same here.
[Nexus 10 Original Android Development] sttovo:
Fwiw- I get reboots watching video with Trinity and KTmanta, so I don't think it's totally a kernel issue. I've not done any additional testing, as the reboots are very random for me.
[Nexus 10 Original Android Development] situman:
Had a hard freeze and reboot on 34 and 4/8 rasbean. Running great on rasbean vanilla and 34. Go figure. Probably some mods to the ROM not agreeing with the mods in the kernel and vice versa. Interactive row BTW.
[Nexus 10 Original Android Development] EniGmA1987:
and no one use to complain about video crashes in either thread until just recently. Makes me think there was an app update a week or two ago for one of the more popular video players that is causing the issue.
[Nexus 10 Original Android Development] sttovo:
I've had reboots in YouTube (direct and watching via the Play Store), MXplayer, and the Time Warner Cable live TV app. Not sure what those would have in common???

It's all totally random for me though. I'll try and grab logs next time.

---------- Post added at 02:04 PM ---------- Previous post was at 01:34 PM ----------

Well, just got the video reboot issue, got a log.

Interesting line is…

[ 952.084049] wm8994-codec wm8994-codec: FIFO error

Nothing else around the error of interest, whole log here, let me know if you can't open it.

[Nexus 10 Original Android Development] jhankg:
I can second this. Random reboots on 34 and 32 with YouTube, mxplayer, and bsplayer using multiple ROMs including aokp pub, cm 10.1, and rasbean.
[Nexus 10 Original Android Development] Poser:
I thought wm8994 is a reference to the audio processor....no?
[Nexus 10 Original Android Development] ThugosaurusRex:
Having the exact same issue he is. Happens to me about 3 times a day.
[Nexus 10 Original Android Development] situman:
U guys should give rasbean vanilla a try with this kernal
[Nexus 10 Original Android Development] sttovo:
Actually, I was adjusting the volume just as the video started and then crashed. Force of habit to make sure the volume wasn't blaring. Maybe it's an audio issue instead of video?
[Nexus 10 Original Android Development] altimax98:
Not that it matters but I get the exact same thing. Kernel is rock solid until I run a video through any app. I'd estimate around 30% of the time it locks, I've narrowed it down to being while it is buffering in my case, either local buffer or Internet buffer is when I notice it most
[Nexus 10 Original Android Development] brees75:
I was thinking the exact same thing. I have absolutely no stability issues on either kernel, can watch movie on Netflix or play game for hours. Load up video in a browser and get reboot. Definitely software issue unrelated to ROM or kernel. And before someone pipes up about vanilla rasbean again, it obviously uses a different driver. Lol :p
[Nexus 10 Original Android Development] brGabriel:
Although I'd like to believe its just an app issue, I'm not completely convinced.

Like others, I also experienced freezes/reboots when loading videos with kernels 32b and 34. So, in an attempt to troubleshoot, I flashed kernel 31 then opened up mxplayer and loaded every movie I have stored on my N10. I did everything I could to trigger a freeze: jumping forward, backward, stopping, starting, etc. but there was no lockup. With the latest kernels, I'd experience a freeze about 1 out of 5 times I'd open a movie, especially if I tried to fast forward or backwards.

While my tests are by no means proof (even to myself) that its 100% a kernel problem, it does at least make me want to avoid the latest versions until the culprit is identified.
[Nexus 10 Original Android Development] jhankg:
I have to agree. As I said earlier, I have experienced random reboots on 32 and 34 while using mxplayer, bsplayer, and the youtube app. I've experienced this on three different roms, so it seems extremely unlikely that this has anything to do with one specific video player app update.
[Nexus 10 Original Android Development] lvnatic:
I streamed a lot of porn on stock kernel and had no issues.
[Nexus 10 Original Android Development] mistermidas:
I literally loled hard as hell just now.
[Nexus 10 Original Android Development] Fidelator:
I'm pretty sure the likes mean that this is an important function of our tablets. :good:
[Nexus 10 Original Android Development] brees75:
Its not an app issue, its a codec/driver issue.

---------- Post added at 06:35 PM ---------- Previous post was at 06:32 PM ----------

Good for you, depends on the video encoding, I can watch Netflix without issues, mainly happens with embedded video.
[Nexus 10 Original Android Development] brGabriel:
If you say so.....
[Nexus 10 Original Android Development] Nasty64:
Maybe the problem takes more than 2.5 minutes to show up? :)

damnnnn

Great job improving on this kernel, it actually made my tablet noticeably better and faster & The only thing I want from this kernel is a CPU OC that'd be greaaaaat.:cowboy:
[Nexus 10 Original Android Development] stonebear:
I got a freeze with 34 when streaming video too. In this case I was using Qloud Server to stream from my PC, I tried to get a last_kmsg but I keep getting "no such file or directory" when I do it manually and Syslog has the option greyed out so I can't do it.

I flashed 31 and went to the same movie in Qloud (it remembers where it last played from) and it froze the tablet again so I flashed TX16 and did the same thing and that did not freeze, so I think it must be a change between 16 and 31.

edit

So, happy with TX16 I ran an Antutu test and it froze and rebooted and this time it let me get a last_kmsg.
[Nexus 10 Original Android Development] ThugosaurusRex:
Does anyone have a fix or know the cause of the reboots? I can hardly watch videos anymore
[Nexus 10 Original Android Development] stonebear:
No, you could just go back to an earlier version though, I never had a problem with TX5G.
[Nexus 10 Original Android Development] morfic:
Well I'll see if it it's relating to the int freq increase.

If I get a chance I'll revert that tonight as a test.

I have no issues playing videos using play movie, YouTube, or flash, so I can't replicate and test.
[Nexus 10 Original Android Development] situman:
All you guys with issues have you tried diff roms? I"m on rasbean vanilla and no issues watching videos or otherwise. In fact its getting better and better as the days go by. In that I mean it has gotten even smoother and responsive.
[Nexus 10 Original Android Development] Syk69:
I haven't had a single reboot since I set max CPU freq at 1300. But before I only really had 1 reboot. Using rasbean latest build.
[Nexus 10 Original Android Development] stonebear:
I am using Rasbean Vanilla right now. :)

Youtube and flash have been ok for me too, it's just Qloud that has done it.

It froze and I had to hold the power button down to reboot and then it wouldn't give me a last_kmsg which is a shame.
[Nexus 10 Original Android Development] morfic:
For reference, I'm on rasbean.

When watching a movie,I usually limit max to 1000, it makes a huge difference on battery, it's a habit now since looking for a way to preserve battery while on plane to Germany over Xmas.

There is not enough load to justify scaling that high.

If the UI was more fun, Netflix plays smooth down to 600mhz.

What I said earlier holds true, watched Tron over hdmi last night, but forgot to limit max, just for reference.
[Nexus 10 Original Android Development] ThugosaurusRex:
The weird thing is that I tried ktmanta kernel, and it has the freeze ups as well. I hope you can fix it, I reverted back to an older trinity version for the meantime :D
[Nexus 10 Original Android Development] iamikon:
This does happen on KT manta as well so probably an upstream issue. It doesn't effect me personally so it doesn't effect all devices
[Nexus 10 Original Android Development] morfic:
Would like to know what apps people use who have freezes and who doesn't

Same for roms.
[Nexus 10 Original Android Development] stonebear:
Only happened to me with Qloud, using Mr Robinsons AOKP and also Rasbean Vanilla. Now I think of it, it did happen with the previous KTmanta too. Seems like that is the same for a few people.

The weird thing is that this seems to have only started happening to people recently.

It might help if people started posting logs instead of just reporting the issue? :)

In my case it could just have been a Qloud issue but it could be relevant that flashing back to TX16 seemd to fix it, unless it was a coincidence.
[Nexus 10 Original Android Development] ThugosaurusRex:
YouTube and mxplayer for me. MX player freezes either at the first start of a movie, or when fast forwarding or rewinding. YouTube seems to be random on its freeze ups.
[Nexus 10 Original Android Development] sttovo:
Here's mine:

ROMs: AOKP PUB, CarbonROM, Rasbean, LiquidSmooth

Kernels: Trinity (latest) and KTManta (last 2 versions since 4/15)

Apps: Youtube (direct and from Play store), MX Player, Time Warner Cable "Live TV" app

I did provide a last_kmsg log, but it didn't seem to have anything useful in it: https://docs.google.com/file/d/0BxHt6Xcz4pjzOFJOZXlxSXBpYjg/edit?usp=sharing

Edit - the error I see around the time of the crash is:

wm8994-codec wm8994-codec: FIFO error

But this seems to be related to sound/volume...

Thanks for taking a look at it. I did check and YouTube shows an update on 4/4, so, maybe that has something to do with it? But, not sure how other apps would share the binaries/libraries from YouTube???
[Nexus 10 Original Android Development] brGabriel:
Same here using EOS Rom. No problems with YouTube or any other apps. Freezes only occur on kernels 32b and 34.
[Nexus 10 Original Android Development] mpmilestogo:
I've had some rather strange issues with 34 with default values and lowering from 620 to 533 on rasbean latest rom. First thing is that chrome would get all flaky and slow way down and when I tried to insert a new url in the url search bar on top everything would just stop and the tablet would restart. This happened a few times but I could never really capture a log on it because of the unexpected nature and randomness. Secondly, I had an issue on the same kernel where something like viewing my installed widgets would cause the entire system to first slow down and then halt and require a power reset. I could never "make" these things happen. Truly random. A benchmark for me is that on the Tx5g kernel these things never happened and the Nexus 10 is extremely stable. I had one single issue with netflix where everything just stopped and the same using the latest youtube dated 4/4. I did lower the CPU down a bit to perhaps 1200 and also reset the dvfs_upper_lock to 533 to try to limit these things from occurring.

I had roughly the same issues on ktmanta using one of the provided configurations so I backed out and first went back to stock and then went to the earlier trinity kernel tx5g.

Sorry these are rather subjective measures but the events seemed truly isolated and completely random. All on rasbean. I have not tried another rom.
[Nexus 10 Original Android Development] TheBlueRaja:
Using the cm10.1 m2 build, never had a reboot until v34 using YouTube.

I did notice on v32 some, flickering using Netflix, but no reboot.

Not sure if it was a one off or not, seems a bit coincidental though.
[Nexus 10 Original Android Development] callummr:
I get freezes in MX Player, most have been at the end of a video or trying to fast forward but there has been one in the middle of a video without any interaction. Same with KT.
[Nexus 10 Original Android Development] morfic:
Thanks for the info, I don't think I'll be debugging KTManta ;)

[ 0.000000] Booting Linux on physical CPU 0

[ 0.000000] Initializing cgroup subsys cpu

[ 0.000000] Linux version 3.4.39-KTManta-g3f3ea4c (ktoonsez@ktoonsez-VirtualBox) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-1ubuntu1) ) #16 SMP PREEMPT Mon Apr 8 19:54:07 MST 2013

I'm noticing all the wakeup and power down latencies around where the FIFO error is too, the watchdog usually bites when the system hangs, watchdogs are safeties for hung kernels.

Thanks for noting the YouTube update, i am a slow upgrader since i like to keep my environment the same to be able to not confuse other changes and kernel issues.

And yes, i do not have the 4/4 YouTube update installed.

I am also still on the experimental RasBean with PUB dalvik i had linked a while back.

Again, slow upgrader, and as Carlo's dalvik choice seems to not be on par with PUB, I'll infrequently sync, build and upgrade this rom.

I'll keep the "But this doesn't happen on TX5G" in mind (even if TX5G is pretty harmless when it comes to "pushing the envelope), I'll be building a test version with lowered INT freq later this week, getting used to the new all nightshift schedule i didn't get to one last night, and not sure how/when i will have time in the future. (I'll have time, just when and all is changing, and i'll do family time first)

I'll be collecting more data like yours meanwhile.

EDIT: Thinking about it, I think i should update the app before the test build, then people can play with GPU min/max much easier and see about what makes a difference (if any) for the reboots. ("Sometime this week")

Since there are other devices that are backlogged too, the app update might be taking a while even if i have time, since i need people testing it on devices i do not (no longer) own.

Thanks again,

Daniel
[Nexus 10 Original Android Development] altimax98:
I have the crashes on YouTube and MXPlayer on Carbon... Looking forward to the fix :) been back on KT since the issue started since I use it for those two a lot.
[Nexus 10 Original Android Development] sttovo:
I'm so so so sorry, I wouldn't ask you to debug ktmanta. I must have grabbed a log when doing the test with ktmanta, but the crash does occur with Trinity. Again, my apologies.

Edit: link to last_kmsg with Trinity, looks a little different, but doesn't seem to be clear where the problem is. I'm on latest AOKP PUB.

https://docs.google.com/file/d/0BxHt6Xcz4pjzYjBTWTZCMzBaU1E/edit?usp=drive_web
[Nexus 10 Original Android Development] morfic:
Meanwhile i rebuilt TX34 with GCC4.8.1, no further changes have been made.

That kernel is on the site.

I attached the patch that is TX34 right now, since i already know this will not be a commit, as some still experience issues.

This way at least noone can claim i'm hiding anything.
[Nexus 10 Original Android Development] stonebear:
My frequencies aren't sticking with Trickster with the new kernel for some reason?

Upon waking it is reset to stock.
[Nexus 10 Original Android Development] Syk69:
Using trickster they stick using frequency lock. Using latest kernel as well.
[Nexus 10 Original Android Development] stonebear:
Thanks, I wonder why it needs it now?
[Nexus 10 Original Android Development] iamikon:
I've always needed frequency lock with trickster and Trinity kernel
[Nexus 10 Original Android Development] espionage724:
I noticed that when I'm setting Performance governor from TKT and setting it to be on startup, my frequency is locked to 1GHz. My min and max CPU speed is also 1.7Ghz. I have to change governors to make it go to 1.7Ghz. Any ideas?
[Nexus 10 Original Android Development] brees75:
Getting great results with new kernel and my tweaks, GPU is scoring almost as well as ktmanta users overclocking over 700 MHz!
[Nexus 10 Original Android Development] Syk69:
What tweaks did you do?
[Nexus 10 Original Android Development] mistermidas:
Those are definitely good scores, but I get close to 7500 on the antutu GPU score with kmanta when I over clock the GPU to 720mhz.

I always bounce back n forth between Trinity and Kmanta kernels though so I'm curious to see how the newest Trinity performs in comparison. Especially since thankfully I seem not to have that video playback bug *knocks on wood*
[Nexus 10 Original Android Development] EniGmA1987:
720MHz GPU results in 58.x fps scores and over 10k 3DMark scores...
[Nexus 10 Original Android Development] Randomwalker:
Could that be throttling? Is it limited to 1GHz right from the get-go?
[Nexus 10 Original Android Development] lvnatic:
Trinity control app doesn't even have voltage settings? Really? My games lag because the GPU is too undervolted, what am I supposed to do now?
[Nexus 10 Original Android Development] brees75:
I saw a bench of 56 fps in the Epic bench, that's what I meant by close. I am sure the scores can get quite high with Overclocking CPU and memory bus, but on this kernel none of that is adjustable and I increased performance with regular system tweaks, and all morfic changed in his latest update was the new GCC. Chill I am not attacking KTmanta, I actually like ktoons kernel I am just having good results with this one and 1fps difference is all I was referring to.
[Nexus 10 Original Android Development] EniGmA1987:
How do you know that your GPU is too undervolted?
[Nexus 10 Original Android Development] lvnatic:
Because real racing 3 stutters, just like when I uv too much on ktmanta.
[Nexus 10 Original Android Development] sttovo:
I can confirm this 100%. I play RR3 a lot and use it as one of my benchmarks for "smoothness". Undervolting the GPU as well as the CPU too much cause rampant stuttering.
[Nexus 10 Original Android Development] morfic:
The kernel needs to reach a point where adding any kind of voltage control makes sense.
[Nexus 10 Original Android Development] espionage724:
Na no throttling, it's 1Ghz from the get-go and never changes either (until I change the governor)

Edit: I know I changed the governor earlier from performance to ondemand and back to performance. I left my tablet idle for a few hours, came back, and it was back at 1Ghz. I'm almost positive it didn't reboot either.
[Nexus 10 Original Android Development] brees75:
I can make it stutter by using the wrong governor/scheduler combo. I use either interactive or ondemand with sio and its smooth as silk.

I also use these sio tweaks:

echo 4 > /sys/block/mmcblk0/queue/iosched/fifo_batch

echo 3000 > /sys/block/mmcblk0/queue/iosched/async_read_expire

echo 12000 > /sys/block/mmcblk0/queue/iosched/async_write_expire

echo 300 > /sys/block/mmcblk0/queue/iosched/sync_read_expire

echo 1200 > /sys/block/mmcblk0/queue/iosched/sync_write_expire

echo 1 > /sys/block/mmcblk0/queue/iosched/writes_starved

echo 1 > /sys/block/mmcblk0/queue/iosched/front_merges

It will also stutter on ktmanta with the wrong scheduler/governor settings as well. I really don't think its due to undervolting.
[Nexus 10 Original Android Development] stonebear:
The Trinity app doesn't have any more functionality than Trickster for example, when it comes to the Manta anyway.

Also, I doubt the GPU is undervolted too much, my N10 hates undervolting but is fine with the Trinity kernel.
[Nexus 10 Original Android Development] samwheat:
sorry to ask again . its there somebody that made otg hdd work with this kernel ? ( i have a wd passport 1gb ) 4x ntfs partition and one fat32 . i only see 2 empty partitions but i can t use them .

maybe i m the only one who has this issues .

with ktmanta it works everytime unless i m 30% battery below .

thank you
[Nexus 10 Original Android Development] DoeBoi:
wow, thank you, thank you morfic, please, let me explain

when i bought the tablet, it always reboots or power down when screen off or while charging, the problem persisted even on the stock rom, i thought the problem to be unsolvable, i was hopeless because i cannot return the tablet to google since it was imported, i was pretty much stuck with it, i tried various roms and kernels combinations, different cpu settings, and other work-around but nothing seems to be a permanent solution, for over a month, i constantly wrestle with it, i thought of selling the tablet or giving it away, but i like it too much, and now after flashing der kernel and all problems are GONE! KAPOOF! just like that, all the random reboots and shutdowns are gone, i am literately in shock, seriously, i'm so happy, i will report back in tomorrow

:laugh::laugh::laugh::laugh::laugh::laugh:
[Nexus 10 Original Android Development] aaron.bufc:
I had similar problems but wasnt sure if it was trinity kernel or rasbean ROM which fixed my problems. Probably a combination of both. I haven't really worked it out as I've stuck with this combo ever since.
[Nexus 10 Original Android Development] mpmilestogo:
I think the Nexus 10 has come a long way since I got it with the random reboots and stutters with things. I'm using the latest rasbean and der kernel with ondemand/sio right out of the box. I'd like to add some of the sio enhancements posted here but things are just so very good right now. With the latest rasbean we also get the PIE navigation which I thought I would never like but it turns out to be basically indispensable to a bigger tablet like the 10. Most of all, thanks to all the great kernel and ROM developers that support our tablet. My take is that better things are right around the kernel er uhm corner :). Look at how far the mainstream Linux kernel has come since I started with it back in 1998. Amazing! If I had the financial ability, I would donate to all the kernel and ROM developers for our tablet. Perhaps in the near future I will. But for now, a thanks is all I have.
[Nexus 10 Original Android Development] 3DSammy:
You are not alone. I had NTFS RO access on both a SD Card and a powered USB HDD when I used SentinelROM/KTManta but since I switched to Tasker650 TX34/Trinity Ten a few days ago that functionality is missing.

I switched to get native CIFS shares working but most important my Plugable Gigabit Ethernet adapter works with Trinity Ten but not with KTManta. I am still struggling to get CIFS working.

It does not seem we can get all we want. I only saw your post as I was checking if anyone else had NTFS issues. I cannot find the "fuse.ko" module which at least gives NTFS RO access.

Oh well.
[Nexus 10 Original Android Development] brees75:
The newest Robinson AOKP pub fixes native otg support
[Nexus 10 Original Android Development] espionage724:
I reformatted my tablet earlier and chose the same ROM and Kernel (TX34 4.8 GCC + latest rbj). I used Trickster MOD to set performance governor, and it's keeping my 1.7GHz speeds. Back before when I used Trinity, it would randomly reset back to 1GHz and stay there (reported it on the previous page).

So basically, it seems like Trickster is working better than Trinity for now. Not sure if it was some weird messup before or what though.
[Nexus 10 Original Android Development] morfic:
Working better than trinity?

You are referring to the app?
[Nexus 10 Original Android Development] the_boo:
Yes he is... He must have some other app or rom that is overriding the trinity app when he tries to use it
[Nexus 10 Original Android Development] espionage724:
Yea my bad, meant TKT.

Still not entirely sure what was up though. I'll give the app another go in the future, but right now my frequency is sticking just fine under Trickster, nothing special needing done. Don't think I did anything out of the ordinary on my previous setup with TKT either.
