You can set the max frequency to whatever you want, but if nothing else sets the frequency (whether a script, system settings or an app) it defaults to 1000.

Not sure what the issue is then. If you could send me the file /proc/last_kmsg right after it reboots it might help me figure it out.

Thank you for sending the files. I've never seen anything quite like these, the same thing is repeated over and over. Are you using HDMI output or anything unusual?
[Xoom Android Development] NeoPreacher:
i don´t use hdmi output. :confused: i did many benchmark tests at this time. also i have seeder, greenify and battery saver pro ( to force wifi into deep sleep while screen is off ) running.
[Xoom Android Development] lepa71:
I can't modify .conf file( can't save it). Permissions seems right,but ES can't write it.
[Xoom Android Development] flar2:
Turn off battery saver pro, or at least the part that puts wifi to sleep. That's most likely the problem.

I don't know what greenify does, but anything that messes with power/suspend stuff can cause problems.

Your system partition is probably mounted read only. ES File Explorer has options to mount the system with write permissions

You could also temporarily (until next reboot) make it writeable by typing the following in the terminal:

su

mount -o remount,rw /system

My Xoom really doesn't like this kernel(vanilla). It reboots when screen goes off. I disabled max off screen setting and S2W completely.

I will try factory reset and see what happens.

Hello, would it be possible to adjust the xoom voltage table maximum please, just the maximum. Not the stock for frequencys. im not sure how to go about doing this, if i do it manually via terminal my xoom is stable on 1.7ghz with an extra 50mv

Also what gpu voltage have you got set for the gpu oc kernel. And for the stock kernel?
[Xoom Android Development] Dollyllama:
I've tried this Kernel a few times now. Running latest cm10.1 nightly. I really WANT to like it because I like the feature set. (CIFS, S2W, etc) but it keeps freezing up/restarting on me. I've tried disabling S2W and it still restarts. Others experiencing anything similar?
[Xoom Android Development] TheMainCat:
Seeing the same thing with EOS4. Builds 189/190 and ElementalX 1.1, together have rolling restarts. Restarts vary from the bootanimation to the loading of the homescreen. Regardless on where the boot gets to, my device will restart over and over and over......
[Xoom Android Development] flar2:
If you have reboots I need /proc/last_kmsg

[Xoom Android Development] recognitium:
I am in the same position. In my case with ElementalX (1.1) I can even hear the sound of one of the processors halting/freezing several times. Before this version, I thought my problem was with GPU overclocking, but with vanilla I had the same issue of random lockups and SODs.

I am testing/trying to use it on my wingray. What info could I provide to help? I am a bit afraid of frying my tablet, but I am more than willing to help.

Another question: what about NTFS read/write support? And, since I'm not sure if it's kernel related, would there be any way to fix the no-pin Bluetooth mouse pairing issue?
[Xoom Android Development] flar2:
This is a minor update that might help those with the screen-off reboots. I wouldn't bother updating unless you have that problem, and even then I'm still trying to determine if this fixes it.

Download:

ElementalX-1.2

ElementalX-1.2_vanilla

Changes:

-disable MMC deferred resume

Hopefully a fix for the people having screen off problems. Other than that, not sure what else I can do after that. I'll probably tweak s2w a bit more.

Try the new build. If it reboots, send me /proc/last_kmsg

You won't fry your Xoom, don't worry about that. You should see what I do to my devices. I've even soldered on them and they survive

NTFS should work, however the write support is limited on linux.

Don't know anything about the bluetooth problem

If coming from a stock root on a Xoom, can I use the latest updated version of this kernel, or do I need to start from beginning and progressively update till I get to the latest version?
[Xoom Android Development] flar2:
This particular problem seems to only affect a couple people. I will send you a pm later tonight or tomorrow.

Just install the latest one.

I don't think any one has tried this on the stock Rom. Do a backup first and you 'll be fine.

Just installed this kernel

I am running dreamcwli's rom and the performance with this kernel has been outstanding so far. Best experience yet on my Xoom. I love the sweep2wake feature. My Zoom is a wingray and I have kept the oc at 1600 MHz.
[Xoom Android Development] rpete76:
OK, so I have been doing a bit of testing and I might have found where my problem lies. I reverted back to the stock cm10.1 kernel and my xoom kept rebooting even at stock speeds. It appeared that mine kept rebooting when the screen was off and I received notifications. I think that the notification sounds were the issue after I had set some dsp settings. I disabled dsp and reinstalled your kernel and so far I have been without any reboots.

I will keep an eye on it and see how I go on and feedback.
[Xoom Android Development] Dyelon:
I just wanted to post here and say that this kernel has breathed new life into my xoom running team eos 3 nightly 155...it was getting slow again as it always does and i was contemplating reflashing or flashing a 4.2 rom. But i saw this and my speed is up very significantly. Swiping through screens and opening app drawer very fast.

Also, I've been waiting for a way to wake the xoom up without pressing that stupid power button in the back and FINALLY you gave it to me! So freaking cool! I find myself just Swiping on and off for no reason lol!

Thanks so much for this, it's truly impressive

First impressions.

Looking good so far on the latest 20130415 CM nightly. I mainly use the Xoom as a daily driver for media consumption. Youtube would stutter on 1000hz.

With EX the videos play silky smooth at 1600hz. I had weird video artifacts at 1700hz and one freeze that required hard reboot.

Will test it but seems the sweetspot is 1500-1600hz. Will get back after comparing battery times.

Re: [KERNEL][Feb12] ElementalX-Xoom-v0.4 | OC | UV | GPU OC | ZRAM | SWEEP2WAKE

I'm usually skeptical of custom kernels, but against my better judgement decided to flash this before this morning's coffee kicked in. Nice work. Love the gesture wake, as now I can truly use the Xoom with one hand (an essential with a 4 month old resting in 1 arm), still experimenting with governors. Big thanks to dreamcwli for making the source code available and to flar2 for taking this a step further.

Re: [KERNEL][Feb12] ElementalX-Xoom-v0.4 | OC | UV | GPU OC | ZRAM | SWEEP2WAKE

So far the interactivex2 seems to be on top as far as user experience goes. Lagfree is good, but definitely stutters in game play. Overclocked to 1.5 with this governor is really snappy. Angry birds hasn't frozen up yet either on this governor.
[Xoom Android Development] flar2:
Yes, I will do that, thank you for the work you've done keeping the xoom alive.

I'm preoccupied a bit with another kernel right now (source was just released today) but I will definitely continue working on this.

to anyone in the know, between smartassv2 and dancedance, which governor will give me the best standby life?
[Xoom Android Development] dreamcwli:
Android 4.2 breaks some interfaces to communicate with kernel. To fix Bluetooth and Wi-Fi tethering we backported many changes from kernel 3.0 as we are still using kernel 2.6.39. I tried to keep whole commit history so you will see more commits for fixing Wi-Fi tethering than other developers. Porting kernel 3.x to Xoom can avoid things like that but it will be a great challenge.

[Xoom Android Development] recognitium:
Just passing by to say that after some testing, with EOS 4 and Elemental 1.2 and OC below 1504 is working pretty consistently, only had artifacts once.

I am puzzled though because with EOS only I have no problems setting OC to 1600, for example. Governor related? I have no idea.

The result no matter the lower OC is great so far! Awesome work.

As a side question, did anybody test it with HDMI and XBMC? I am thinking of acquiring an hdmi cable...

Just a quick question... would I flash the kernel before or after installing the GAPPS? on a EOS4? :confused:

XBMC and GPU OCd EX1.2 issue

As a side issue, I just tried to test XBMC (March 3rd XAF build of XBMC for Tegra) with Oc'd ElementalX 1.2 and it crashes after a couple of seconds it is open. I had to revert back to vanilla for it to work. Anybody else having that issue? Would it be helpful if I sent logs with Oc'd EX1.2 and trying to open XBMC? If that's the case, how could I get and send the log?

The kernel must be flashed before gapps in TWRP, else no boot. So eos, kernel, gapps

OC'd GPU EX12 and XBMC app crash

Actually for me after the first builds it has been pretty consistent with my XOOM and EOS4 builds. Totally usable. I have watched many movies from 1Channel and accessed my central library with no problems. But with EX1.2 I couldn't even enter the app ... And since with EX1.2 vanilla it's working, I assumed it was my GPU OC. Thanks anyway for the thread link, I will investigate further at a slow pace, to see if with any kind of tweaking I can make EX1.2 with OC'd GPU work with the build I am using of XBMC.
