hi faux,

been a while since i used youre kernel on the sensation and i decided to try youre latest b2 kernel.

could you take a lok at the log i attach?

i picked the phone from my pocket, turned it on and unlocked it with pulling the ring.

i got the the homescreen but it didnt display it and the phone became unresponsive:(

hope anything usefull is in there

thnaks for taking a look

edit: ohh before you ask it whas on android 2.3.5 with sense 3.5:D
[HTC Sensation] vcoolvin:
Hi Faux,

Have been using your kernel for a while now... That new ones are amazing and i really thank you for your hard work. I just get a great performance and a good battery life for my usage. Using ARHD 4.1.9 with 0.2.8b+ kernel, my phone was performing very well. giving me more than a days battery life for my kind of usage. But last night something weird happened.

I realised that i had left my6 notification volume down in the night and wanted to increase it so when i opened volume in sound settings my phone froze on that screen but the status bar was working and then i got force close for sound setting and so i tried again and then again the samething. Then all of a sudden my screen went blank with just the status bar and the capacitive LED on, but this time nothing was responding and so i had to use the three finger salute (Volume up+ down + power) to restart the phone. Attaching my last_kmsg if that would help.

Oh also forgot to mention that after my phone restarted all my sound settings had changed to something else. Wanted to add one more thing on 24th whenever i was getting a message my phone would give the notification sound but right after that it would start playing a voice recording i had done (that was really weird at 1 AM when i was fast asleep with my ear phones still plugged in my ear. Scared the hell out of me. Do you think that it is got something with the kernel.

Thanks for everything, and sorry for the long story.
[HTC Sensation] miniterror:
Lol,

This sounds the same i had only i got the unresponsive screen after unlocking the phone by pulling the ring in lockscreen:s
[HTC Sensation] faux123:
You have a very serious problem with your errors. For some unknown reason, your mpdecision binary CANNOT get any memory from the kernel... that's the main reason for the crash. You literally ran out of memory as far as mpdecision is concern... which means you have a major memory leak of sort from some rogue application....
[HTC Sensation] faux123:
Your error is not as serious... for some reason, the kernel was blocked (which means it was waiting for something) most likely network related... something timed out... were you using some networking related apps at the time? Maybe an app running in the background with internet connections waiting for something to complete?
[HTC Sensation] red8981:
Try not flash the kernel reset.

After you flash your from and boot up, go back to recovery and wipe cache. Then flash the kernel. Boot up, if it still reboot, try fix permission
[HTC Sensation] miniterror:
Thanks:)

I have no idea wich or what it is,

I do know in system tuner pro when i look at the logs tab and filter it for error its empty, but when i look at the warning page its loaded with this.

Do you think its related?

I asked multiple people in the team but no one knew and sergio never replied on it:(

Hey Faux!

I was looking in Market and tried to back out. The phone vibrated 2 times and then was completely still. Screen was on but completely frozen.

3-finger-grip and here's Last_kmsg =)
[HTC Sensation] vcoolvin:
Hmm, I went through your last_kmsg.... Interesting.... very interesting :cool:

I didnt understand anything from it :D lol wish i knew a little bit to atleast understand this language. But i think it is better left for the pros.

lets see what conclusion faux comes to after seeing the file.

I hope i didnt commit any crime for which i was punished by that freeze :eek:

I consider myself very lucky to face issues very very rarely.
[HTC Sensation] faux123:
You have a dreaded ZRAM bug... ugh... I will disable ZRAM again in the next beta or final :(
[HTC Sensation] remus82:
Would zram issues become more apparent when the phone is underclocked? In my previous phone, having a lower voltage for the chips would cause swap to malfunction. The phone would slow down instead of making things smoother!
[HTC Sensation] faux123:
ZRAM bugs are very difficult to debug. Swapfile/Paging actually causes a CPU exception (a recoverable version), then the kernel handles that exception by grabbing the paged/swapped out memory and place it back into main memory. So whenever you have an issue with paging/swapfile, you have to troubleshoot 2 different exceptions... which makes things almost 2x difficult.
[HTC Sensation] Gtj94:
Do you mean undervolted? because if the phone was underclocked, slowing down isn't that much of a surprise...
[HTC Sensation] Mathias1:
Thanks for input.

Is it enough to disable ZRAm through swapoff /dev/block/zram0 as a workaround?

Seems like ARHD has Zram enabled at startup..

Also, I really can't notice any difference with or without Zram..

Is CompCache more stable/more noticable?
[HTC Sensation] rawrfische:
Aww boo. Would the problem be solved if people simply commented out the zram activation in their init.d or init.post_boot.sh scripts?

I've never had any stability issues with your zram enabled kernels and would hate to see the feature go away again. Surely I can't be the only one?
[HTC Sensation] faux123:
Yes, just disable the ZRAM script should make the problem go away if you have ZRAM related issues.

PS: CompCache is very very old version of ZRAM...
[HTC Sensation] Hawke84:
Noooooooo
[HTC Sensation] remus82:
Yeah undervolted. My bad!
[HTC Sensation] TheUntouchable:
+1, dont wanna miss it again :(
[HTC Sensation] vcoolvin:
:eek: i didnt refresh when i replied my last post and now i realise there were so many posts between them.

Thanks faux for your reply and your conclusion. I was at home and i have wifi on all the time at home, yes you are right i was using kik messenger at that time (sorry forgot to mention that) and so when i was getting messages the notification sound was too low and thats when i tried to increase when i got setting sound force close.

Also i had another boot around an hour ago and again this time while using kik i clicked a pic with flash on and my phone froze and everything just went down no lights or anything (reminded me of the camera issue i had earlier but not sure if it was this kernel, probably it wasnt).

Anyways my conclusion is that i think i messed up a bit had done a nandroid back up to try ARHD 5.x.x, but then soon came back and restored my back up and i think that might be the issue. will do a full wipe and install the ROM again and then flash the latest Faux kernel (hoping will have a new one by the time i am done, if yes then will flash the latest of latest :D )

Thanks once again Faux. Hope you had a wonderful christmas.
[HTC Sensation] PaulGiz:
[ARHD4.1.9][2.8b2]

Don't want to jinx it, but still absolutely no problems. ZRAM is definitely enabled and working on my phone. I was one of the ones who had ZRAM crashes with 2.6 kernels.

I am running 384/1512, intellidemand, bypass daemon. No UV.

I haven't had a freeze, crash, black screen or anything since loading it with moderate to heavy usage.

It is disturbing that we can't count on the ZRAM, I guess. If it were gone I'd miss it as I have noticed difference with it on when moving among different open applications.

Keeping my fingers crossed it stays this way, but I'm thinking something would have come up in the last 3 days.

P.
[HTC Sensation] Mathias1:
Maybe I was wrong, I meant the latest feature on 2.8 beta..? Or maybe it was CompCache..?
[HTC Sensation] takuhii:
Comcache is the older version of ZRam, they are TECHNICALLY the same thing...
[HTC Sensation] ein777er:
Dear Faux!

I think the most thing to get ZRAM freeze is to much undervolt. I never had any freeze with 1.27 and -50mV. With 1.28b2 my phone froze while copy an nandroid backup via myphonexplorer and only there, it is reproduceable. With -25mV all is fine :-)

1,56 Ghz - 1075mV

ARHD 3.6.8

Sleep gov. 192 - 348, conservative

Wake gov. 348 - 1,56 ondemand

kind regards

[HTC Sensation] remus82:
I think you mean cleancache
[HTC Sensation] Mathias1:
That I meant! :D

So, is it more stable and noticable than Zram? =)
[HTC Sensation] remus82:
I don't know haha. You gotta ask faux to explain in layman terms. :)
[HTC Sensation] erraggy:
+1

I second this experience. The only difference is that I've always used -25mV and not had any ZRAM issues.
[HTC Sensation] Kohr-Ah:
Unfortunately in the past even some with -25UV have had crashes.

The issue is sometimes zram causes kernel panics.

If it works for you undervolted keep going for it. Hawke and I rarely had issues with ZRam and undervolting.
[HTC Sensation] tibere86:
I have always ran faux's kernel since intellidemand was introduced as follows:

-Wake Governor = Intellidemand

Wake max =1512000

Wake Min = 384000

Sleep Governor = ondemand

Sleep max = 540000

Sleep min = 192000

My question is would I get better performance allowing intellidemand handle the sleep profiles itself (putting the OC Daemon in bypass) or allowing the Daemon to handle it as I have it currently set up?
[HTC Sensation] malybru:
Hi,

I think "Intellidemand" was created to do a better job of handling the sleep/wake states.

So,set bypass,

choose max/min frequency,

select intellidemand,

apply.

i had a really bad problem with 0.2.8 yesterday, fully charged it and then went out.

It does the normal thing of staying at 100% for a while and then dropping to 99%.

After that I sent a few txts and looked at a website for like 5 mins and it dropped to 95 and then after a min on standby it dropped to 90 without going to 94 93 92 etc

so I had to reflash bricked and then it went back to normal.

Forgive me for being a noob and also if this has been asked before but can i install this kernel on stock s-off rooted 2.3.4.

If yes, how? Can i use the method from mikes HD rom installing modified 0.6 followed by 0.9?

Is there any reason why i shouldn't be doing this?

This is why I don't like mpdecison.. it is a userspace binary and it's closed source, I have no IDEA what it is doing to the kernel...

@faux here is the enabling code mike puts in his init.post_boot.sh:

# Enable ZRAM (kernel must support ZRAM feature!)
stop mpdecision
mkswap /dev/block/zram0
swapon /dev/block/zram0

Does this effectively disable mpdecision? Or only temporarily?
[HTC Sensation] ifti_a:
Hey faux

I'm not 100%.sure about mpdecison but its stock in.ARHD I haven't touched the mpdecsion at all.

#stop mpdecision

mkswap /dev/block/zram0

swapon /dev/block/zram0

Hi, I just jumped into using the kernel. I have noticed a couple things. First I am using the 0.2.7 ultimate edition kernel and OC to 1.73 I am using it on the elegancia rom sense 3.5 rom. I have an issue with the fauxclock app. I get a FC on it after reboot but then it is fine thereafter unless I reboot again? Also when I check the OC app I see that it reverts to the intellidemand gov, from the ondemand? If I change it back to ondemand it seems fine unless I reboot? I have tried to reboot with set on boot checked and unchecked, does anyone have any suggestions?
[HTC Sensation] Hawke84:
Do it, reboot the phone and it will be switched off. No won't damage your phone, lost of users turn it off cos it can cause problems. All Arhd used to come with it off by default. Adding the # just means the line doesn't get read by the phone but its still there if u want it back on..

As for whether u should turn it off, faux is best one to answer, but that should fix your issue.
