Can you tell what you was doing on phone then. Maybe this will bring some light on what exactly is crashing.

Playing 'Where's my water' for like an hour on airplane mode. The screen was scrolling at that time and i was flicking down on screen. Then it freezed for 4 seconds until the screen gone dark to reset.

I will setup a logcat again to make sure we've covered all buffers at least once.
And i would like to find something to analyze the kernel.

And as I'm writing this, reading on a different tab about kgdb it crashed again while scrolling/flicking. CMD52 is still there. Many CIFS lookup errors (CIFS VFS: Unexpected lookup error -20) as if i had forgot to unmount before disconnecting wifi. CIFS generally could be a good point. I'm using that daily with SuperSU (to mount system-wide) that has potential (--mount-master might be done with dirty tricks). Maybe i should update SuperSU or try a different approach just to make sure.

su --mount-master -c busybox mount -t cifs -o username=$username,password=$password,$mountoptions $host $folder

20141111 lasted two days without crash and if i remember correctly i didn't use CIFS there. Need to test that...

Scrolling you say. Maybe this is mdss issue. Maybe I should revert all mdss changes. Except some fixes like brightness. I don't like mdss code at what state it is now anyway.
I don't think CIFS or SuperSU is involved here. You can try to remove SuperSU and try it with ordinary su and mount. Who knows maybe it can cause some troubles.
Anyone else have crashes?

I would have done that immediately if it would have been possible. Proper mounting never worked for me even though CM included a fix long time ago (restricted slave mountspace).
But on another try 5 minutes ago it did finally work properly out of the box indeed so i will drop --mount-master of course. If it doesn't change anything i will test omitting CIFS completely.

There were some people reporting similar crashes but i don't think they've done the same stuff i do with CIFS. We will see...

MDSS could be a good point either. When the screen freezes and goes dark you can notice some white horizontal lines on screen (a proper shutdown doesn't show this behavior). That somehow always reminds me on initialization phase on bootup right before the bootanim starts. There, the screen sometimes comes up with a 50% screen filled cyan flicker. But who knows, that's just a wild guess so far...

I think i've found the cause for the audio lag. It seems to be MX Player itself on H/W+ mode only. Using H/W mode seems to work properly. The H/W+ mode can amplify the volume up to 200% so i guess the '+' means they are additionally preprocessing the streams that causes the lag. Pffff.....

Btw, i tested CM screen recording ('screenrecord' binary). It works wonderfully (nearly no lag or frame drops). It just needs some extensive bitrate for pristine quality (i've picked 32Mbit/s) as its AVC/Baseline@L4.2 only.

Edit: Is it just me or is the 'clock' not working (fc) in landscape mode?

Hm. So it looks like theirs audio preprocessing. Maybe coz of qc sound effects.
There is patch commited yesterday for clock.
Found a fix for blue screen beam and iommu page faults for now. Will look more in mdss code.

@solk2, is there some place where I can leave proposal for new CM feature?

I'm missing one Jolla feature, temporarily lock screen rotation.
On Jolla it work by tap and hold screen while rotating phone, keeps current screen positioning until rotating again, this would be nice feature on Android too.

At least good to know there are others who also have the crashes so it shouldn't be an isolated problem on my side.
Full dmesg is running. I hope it gets synced before crash and leads to some useful informations.

Will report back...

Damn. I forgot completely that I've update EGL libs in my home builds. Maybe thats EGL. Then it would explain why I don't have these reboots. But anyway I am reworking mdss driver currently. And have some updates in current build thats could be a reason too. And as I understand phone crashes only when frames is updated on screen.

Yeah, it must be something you changed not too long ago. I did not experience the reboots the first weeks I used the rom.

Hi all, I want to buy this device and want to know how`s CM11 working on it?
Is it stable enough for daily usage?
Are there any device maintainers to proceed further development of CM?

Thanks in advance for any helpful replies!

I have found the official CM to be stable for daily use and a great rom. Right now the newest dailies are not completly stable. Some code got changed that caused random reboots.

There is also another unofficial CM made by arter97 ( which I am using while waiting for the problems to be solved with the official one.) It is completly stable. He has uploaded a working lollipop CM, which is not yet good enough to be a daily driver, but shows promise.
