If someone has time can they post a spreadsheet with uv scales they have been using on different frequencies..

I would do it.. but I am about a week out before having time to read through all the posts to pop them into a spreadsheet..

This would be one of those indispensable quick look sheets many of us can revert back to on the updates..

I am feeling a little left behind..lol.. as we are up to 20 and haven't had time to play.. I think I am still on 17a and its been fine..

Good work big C...we are all running better machines due to your tireless nipping and tucking..

That is exactly what I had done - but did not make much difference.

When I selected the option to wipe the cache in CWM Recovery there was a message which said something about can not mount or something like that - can not remember exactly what it was - but I did do all those wiping actions using CWM Recovery Advanced Options. Surprisingly there was no message which said "ERROR" as such - there was one message saying 'can not' but it sounded more like an information message rather than a warning - so I more or less ignored it.

May be I should wipe it completely including my data on the tablet and start from beginning.

I would do that later on today and report back.

But is there a log created during the boot process and this unwanted looping reboot process? Is there an equivalent of 'dmesg' as available on desktop PC Linux?

Kernel Automaitcally OC'd?

Hi

I have Clemsyn kernel one of the older version without any OC. If I flash the latest one, does it mean it is already OC'd? If so is there a way I can disable it?
[Eee Pad Transformer Android Development] vlbaindoor:
What is the best way to wipe it all clean and empty, please?

I used the terminal App on my TF and looked through /sdcard and could not find anything which would be a log file - there was a log file created by my earlier Revolution ROM installation - but nothing to do with Revolver.

What would be the name of the file anyway please?

Thanks for that - I think Clemsyn has already mentioned that if I simply install the kernel and do not have any CPU Tuning Apps then the kernel on its own would not overclock.

Looks like the answer for me is to wipe everything clean - as I seem to have some remnants from my earlier Revolution installation, and start all over again with Revolver installation.

The question I have is - what is the best way to wipe it all clean and empty?
[Eee Pad Transformer Android Development] baseballfanz:
The kernel doesn't put you in oc.

The kernel has the ability for you to oc using setcpu or similar app.

So just by flashing you'll be ok if you don't wasn't to oc

Using v19 with the usb lag or the newest v20 which is awesome on Revolution i'm unable to see my NTFS usb hdd. I'm looking in Removable right? Cheers.
[Eee Pad Transformer Android Development] chatch15117:
The only kernel that automatically OCs is the 14b version for 3.1. It will boot at 1400MHz. The rest are stock at 1GHz
[Eee Pad Transformer Android Development] Backwardsblade:
Rock solid on 20b. Had random reboots on both flavors of 18 and 19. Stock volts/OC to 1544. Well done!
[Eee Pad Transformer Android Development] vlbaindoor:
Solved - Now using Revolver ROM and Clemsyn's kernel 20

Well what can I say?!!!

It looks as though a Theme was the culprit for all the reboot problems I have had. I had used the theme available as part of the Revolver Parts - the one that is available from menu option through Revolver Parts.

What I did was wiped my TF clean - including my data etc, re-installed the ROM and the Parts all over again. I also installed the Clemsyn Kernel 20 that is available through the Parts add-on again and rebooted with the new kernel.

Now everything seems Ok. I connected my TF to my Panasonic TV through HDMI, it seems to work OK, connected the Charger to the dock and it was happy this time - did not reboot.

The main difference is that I did not install the theme - but left it with the default theme.

So it looks like it was the theme which was the culprit - probably not the kernel itself.
[Eee Pad Transformer Android Development] thebadfrog:
You could saved yourself a lot of pain by checking the thread for the theme

Bugs: Dock Related Only: Mouse Gesture Cursor Only/Regular Cursor is not there for some reason although the image is, Bootloop when you plug dock up to charger

[Eee Pad Transformer Android Development] henel321:
Anyone else experiencing worse battery performance with 20B? Mine doesn't seem to deep sleep in the same way any longer. On some wake ups Wifi takes a lot longer to activate then on stock revolver 3.2 kernel. (Like it is switching wifi on/off 5-10 times before it has the time to connect.)
[Eee Pad Transformer Android Development] vlbaindoor:
The thread for the theme? Ok - that means a different thread right? And possibly a different sub-forum related to themes and so on.

But I would check a separate thread only if I suspect something. The fact that the Revolver Parts presented me this option meant that it was part of the Revolver Parts! Pun unintended.

Anyway thanks for all the help you all gave.

running clemsyn 20b kernel since yesterday, oc to 1544mhz and -50mv. very quick and stable. definitely the best combi.

tried 20a too, but it freezed several times when I surfed and watched YouTube (oc to 1472mhz and -50mv).
[Eee Pad Transformer Android Development] XsceneXhippieX:
this kernel is awesome, whatever clemsyn does different, it is working, and PLEASE keep it up! this kernel has become the only thing that runs custom roms smoothly on my tablet (every tablet is different and all, mine LOVES this kernel lol) it makes my friends with iTard devices jealous at least, the point of this post is to point out to the dev that clemsyn v20b + revolver rom has officially converted exactly 4 DIE HARD apple fanatics to android lovers because of the performance experienced during the use of my tablet, honestly the ipad (&ipad2) are VERY smooth running devices, and apple fanatics selling their ipads for transformers it pretty much some of the best props you could recieve being involved in android tablet development with any device in my opinion :) hope this fact made someone else grin menacingly }=)>
[Eee Pad Transformer Android Development] Bjd223:
This happens to me when I undervolt. Try removing undervolt, rebooting and then check the camera.

I noticed that if I undervolt under 1 GHz and then the tablet goes over 1 GHz the camera app will freeze.

So either run at stock 1 GHz with undervolt

or

Undervolt only over 1 GHz

or

Try to undervolt a little less under 1 GHz and hope it works. But I think there is something else going on because when I undervolt under 1 GHz 912 MHz will freeze the camera even at stock voltages.

It is very strange.
[Eee Pad Transformer Android Development] a.mcdear:
Is it just me, or does anybody else tf101 seem to lag a bit more than normal after getting back to the desktop after running an app with 20b?

I'm going to go back to 18b for a sec to see if I'm imagining things, but 18b seems to be faster/smoother than 20b..
[Eee Pad Transformer Android Development] Globespy:
how would I know that my TF rebooted during the night?

I'm running 19b and it seems to be very stable on HD 1.2.1 - last 3 days I wake up and its operational, unlike previous kernels that had gone into SOD.

How would I know if my TF had rebooted during the night when the TF was in sleep mode?

Thanks
[Eee Pad Transformer Android Development] thebadfrog:
If your overclocking then dont set it to overclock on boot. If your not overclocked then it must have rebooted

Not overclocked, only undervolted on frequencies from 1ghz to 216mhz.

here are 2 reboots today at work (on a 802.1x network). also had disconnects. at home everything is fine (WPA2-psk network) - no reboots, no disconnects. (reboots seem to happen while docked, haven't noticed one yet on tablet only)
[Eee Pad Transformer Android Development] mike1986.:
Conservative governor is in 20 as well as far as i can see :)
[Eee Pad Transformer Android Development] georgica81:
just installed v21a and i notice a lag in drawing the widgets (when rotating the tablet). also antutu went down about 300 points. most significant are 3d graphics (about 50 point from 1301 to 1255) and the biggest hit on database IO - 485 vs. 290. i did a wipe cache and wipe dalvik cache, but still no major change.
[Eee Pad Transformer Android Development] jwilliamf:
been running 21a for 3 hrs now, and it seem rock solid like 20a. No reboots, no lags, NTFS Good, USB still good, no problem with stock browser, no problem with youtube videos. Very stable at 1544 with -25uv.

Good Job Clemsyn!!!

A small thanks (7E566069CG945380B) to clemsyn for developing the best kernel.
[Eee Pad Transformer Android Development] clemsyn:
Its been in the kernel ever since but the latest calls it when the screen turns off then calls the default governor when screen is on.

BTW, I am uploading another 21a since I forgot to update the wifi and scsi driver when enabling JRCU_lazy.

Update, latest 21a is up.

BIG THANKS :) It's greatly appreciated
[Eee Pad Transformer Android Development] Globespy:
as someone earlier pointed out, reboots seem to happen when tablet is docked far more consistently than when not docked. I'm having this issue and have had it in pretty much most of the kernels.

Clemsyn can you speculate as to Why? .. do you have a dock yourself, and if so are you seeing this?

If you don't have a dock then perhaps there is something from the stock kernel not being translated properly in your kernels? just a suggestion.

Thanks for all you do.
[Eee Pad Transformer Android Development] thebadfrog:
What rom are you using and are you using a theme? I have a dock and am not seeing this issue. I know it happens with revolver and the x theme as this is a know issue.
[Eee Pad Transformer Android Development] Globespy:
Using HD 1.2.1 - no themes, and currently v21b kernel set to stock frequencies with conservative undervolting.

---------- Post added at 05:27 PM ---------- Previous post was at 05:24 PM ----------

clem, can you clarify that in v21b when my screen turns off, the kernel will automatically switch to conservative regardless of my setcpu settings? I don't have any profiles setup in setcpu (such as screen off) so can I assume that this new kernel does this function automatically?

Out of interest, if I did have a screen off profile, would this automatic feature in the new kernel override the setcpu profile? Worth asking as many people create a screen off profile.

Thanks.
[Eee Pad Transformer Android Development] Popsiclestand:
I agree. I have had this consistently through all kernels I try. Some have more frequent reboots than others but all have reboots when connected to the dock...

No reboots whatsoever when not connected to it.
[Eee Pad Transformer Android Development] gbroon:
I did a little test on this, I used set to setCPU a profile for screen off to be powersave with interactive as default, disabled lockscreen and turned screen on and off with setCPU open to see what governor it showed. When I turned screen on it looks like it is switching from conservative to powersave and then either sticks on powersave or goes to interactive, once it also changed to ondemend for some reason. When the profile was turned off I could see it going from conservative to interactive as its supposed to. This was 21b, revolver 3.2 rom, no overclock or undervolting set.

It does seem to interfere with SetCPU profiles.
[Eee Pad Transformer Android Development] clemsyn:
Thanks for the info. I don't use setcpu but instead have PimpmyCPU so I decided to add this conservative screen off profile. I thought it would be overidden by setcpu but instead it seems to initially do conservative and then use setcpu.

---------- Post added at 01:23 AM ---------- Previous post was at 01:22 AM ----------

I do have the dock (again, thanks for all who donated) but I never got any reboots but I am currently in 21a. If I do get a reboot, I think it might have something to do with the JRCU_lazy implementation. If you could test 20a for me delete your voodoo module and let me know if you still get reboot, I will appreciate it :)
[Eee Pad Transformer Android Development] Globespy:
will do. I will see if 21b causes the issue when I wake up tomorrow morning, and if it does I will remove voodoo and try 21a and let you know.
[Eee Pad Transformer Android Development] Danzano:
I was testing 20b with prime and hd roms got a couple reboots but i to was using set cpu for root users not pimp my cpu also i tried pimpmycpu it only showed in portrait which was annoying enough to make me switch alone.

Ill try ver 21 soon i dont have paid vodoo or vodoo in either roms so might try the a version this time round :)
[Eee Pad Transformer Android Development] juliensch:
im on revolver, i was running kernel 13, i tried th 21 but i had trouble with wifi, when TF back from sleep the wifi says disconnected, and in the setting it loop saying turning off, turning on the wfi...

i did cache and dalvik clear, try to reflash 3 time...

i use set cpu

no luke, so i came back to 13, now everything ok.... if yo have any idea?
[Eee Pad Transformer Android Development] flolep:
No, as clemsyn said, please test 20a, not 21a, because in 20a there is JRCU disabled and he wants to know if it's the cause of reboots... And danzano, the same for you...
[Eee Pad Transformer Android Development] JeeHaa:
Same here on Revolver 3.2: wifi issues on kernel 20 (no Dock). Additionally I noticed that the TF did not go to sleep mode any more, it drained from 100% to 30% battery during the night, and looking at battery status is was awake all that time.

I reverted to Revolver Part Stock kernel, which instantly solved the issues.
[Eee Pad Transformer Android Development] Danzano:
I was on 20 had Reboots etc that's why was hoping 21 is fixed version
[Eee Pad Transformer Android Development] gbroon:
---------- Post added at 01:23 AM ---------- Previous post was at 01:22 AM ----------

It could be a problem with SetCPU I suppose, when I get in later I'll try with PimpmyCPU and see what that does.
[Eee Pad Transformer Android Development] georgica81:
so... with v21a I didn't have reboots yet. but the wifi still disconnects.

edit: oups! spoke too soon. just had a reboot. the tablet was docked, sleeping (but the dock wasn't closed), I pressed a key to wake it up and bang - reset. I'll grab the ramdump and add it later.
[Eee Pad Transformer Android Development] flolep:
Yes, but you were on 20b... Clemsyn and me are telling you to try 20A... 20b has JRCU, 20a has not...

Georgica, the same, could you please try 20a... 21a has JRCU too...
[Eee Pad Transformer Android Development] georgica81:
i switched to 21a because i was getting reboots with 20a... another funny thing - it wasn't a "full reboot". there is no ramdump (it's supposed to be in /sdcard, right?). i just had the asus animation screen, but not the initial asus eee pad logo.
[Eee Pad Transformer Android Development] Globespy:
rebooting on v21b

Hey clemsyn.... As my last post mentioned, I was going to try v21b overnight with just the tablet to see if it had any problems. Sure enough this morning I noticed that the battery drain seemed to be a good bit below what it normally would be if I left it fully charged at midnight and switched it on 9 hours later. When I opened the sd card folder, there was a ramdump.log - I'm attaching to see if anyone has any ideas on why it rebooted?

I will try v21a as you suggested.

If I'm getting reboots without being docked, I have to go back to v19b or maybe even v13b.

Thanks.

---------- Post added at 10:26 AM ---------- Previous post was at 10:21 AM ----------

Are you sure you are correct? The OP indicates the only difference is that 21a does not have voodoo, no mention of it not having JRCU disabled.

I'm thinking clemsyn thinks that it is something to do with the paid version of voodoo that could be a problem.

---------- Post added at 10:38 AM ---------- Previous post was at 10:26 AM ----------

BTW - if I want to know if v21a will cause reboots (seems to happen in sleep mode with the other versions), is there a way to quickly force my tablet into deep sleep without having to wait for it to do it itself?
[Eee Pad Transformer Android Development] jwilliamf:
Mr.

Try 20a. 20a does not have the voodoo and no JRCU_Lazy.

Voodoo is NOT the problem for reboots so clemsyn is trying to find out if JRCU has something to do with the reboots.
[Eee Pad Transformer Android Development] Globespy:
My bad, missed that it was v20 not v21

Thanks
[Eee Pad Transformer Android Development] flolep:
Wowwww ! Finally !! :p :p
[Eee Pad Transformer Android Development] Globespy:
:p on v20a now but noticing a real drop in UI performance. Noticeable lag across the board. Even if this doesn't reboot, I can't live with it as a daily driver. :(

Maybe I will upgrade to HD 1.2.2 and as suggested remove setcpu or any other cpu Apps just in case it was setcpu causing the problem.

If that fails its back to v13b which I know has no problems at least on my TF!
[Eee Pad Transformer Android Development] flolep:
Yeah, I know... JRCU is improving performances for me too... But, at the opposite, I don't have reboots with the dock and JRCU, only if I push it to the limits...

I don't know if Clemsyn will be able to keep JRCU for performances and correct the reboot bug in the same time :(
[Eee Pad Transformer Android Development] XsceneXhippieX:
sorry if this is supposed to be an obvious conclusion to come to, but on ARHD 1.2.2 should i use v21a, or v21b? im stressed out and cant think straight right now
[Eee Pad Transformer Android Development] zephiK:
1.2.2 comes with 21a. No need to flash this kernel over that ROM since it was included.
[Eee Pad Transformer Android Development] gbroon:
I have tried a few other things, PimpmyCPU works because it doesn't change the governor it just underclocks to the lowest frequency if you choose the option to do so, effectively powersave anyway but without changing the governor.

I have also tried tasker to set activities to change governor to powersave on screen off and interactive on screen on and it shows the same with it being conservative when you turn on, changing to powersave and then randomly either sticking in powersave or then changing to interactive.

The kernel takes preference on screen off and doesn't allow other apps to set it, it also causes problems with changing the governor back when the screen is turned on.
[Eee Pad Transformer Android Development] clemsyn:
If v13b is stable for you, this kernel doesn't have any overclock in GPU 2d/3d so maybe overclocking the gpu is causing issues with your TF.

---------- Post added at 09:22 PM ---------- Previous post was at 09:20 PM ----------

Might be due to your OC settings if there is no ramdump.
[Eee Pad Transformer Android Development] khro1:
for me 20b more stable than 21.

while surfing got reboot on 21b, 20b works solid.

interactive, max 1680.

clemsyn, can u make semi-extreme kernel ? :rolleyes: like 12extreme.

on 12 extreme my device passes antutu benchmark at 1680, but hangs and reboot on 3d test with knights at 1712

+ 1 I'm still ok with overclocking but my tablet is rebooting after its not been used for between 6-8 hours and is in deep sleep. This is the same issue i've been having with pretty much all of the kernels beyond v13.
[Eee Pad Transformer Android Development] clemsyn:
Version 13 didn't have an overclocked 2d/3d GPU and the higher kernels did, so an overclocked GPU might be an issue with your tegra.
[Eee Pad Transformer Android Development] woti23:
i think you have to do it in an init.d script, works for me

and positive values: UV, negative values: OV
[Eee Pad Transformer Android Development] Globespy:
Hmmm... I would have thought that if the GPU was the problem, it would be more inclined to show up when highly overclocked and playing graphically intensive games? Not when the tablet is not overclocked at all and is in sleep mode? I don't overclock anymore as the performance increase versus battery life is not worth it to me. So why would stock frequencies cause this instability on a tegra that is able to run at 1.68ghz for hours in end playing tegra optimized games?

Can you see anything from the log I just posted? Sorry, I have no idea what to look for.

http://db.tt/I5dNsj0Y
[Eee Pad Transformer Android Development] clemsyn:
Intensive games is more on 3d, you have to factor in 2d side of the GPU. CPU speed is different from the GPU. If you reboot using Default CPU speeds, then it is more than likely the other overclocked timings (GPU either 3d or 2d, VDE, MPE etc..) is causing the issues. Version 13 has VDE, MPE timings overclocked but it doesn't have GPU overclocked so you don't have issues with the vde/mpe being overclocked but your GPU does.

I checked the log and there is no mention of any Preempt errors so it is more likely an error in the GPU side.

I will try building a kernel with no overclock on the GPU if you want but please give me sometime.
