[TouchPad Development] woodytrain:
Finally had an opportunity to test CM11-3.4kernel (DataMedia) ROM for the first time (02/28 nightly). Here is my experience...

Soon after initial boot into CM, while I was viewing "Settings > About Tablet" I allowed the device to go to sleep. Within a few seconds of the device going to sleep, the screen spontaneously flashed and the device rebooted on its own. Then once again, after navigating to the home screen, I allowed the device to go asleep again. And again the device shut down. But this time did not reboot on its own. I had to hold down the Power+Home for appx 30 seconds to power up the device.

After the third reboot, did some more testing for almist an hour (no SOD's). Wi-fi and Google Play Store seemed well behaved. Bluetooth paired and connected with my headset, laptop and HP Touchpad Wireless Keyboard, all at the same time.

Camera worked, although a bit grainier than aI remeber observing in WebOS (Nexus 7 camera app worked but native camera did not, as suggested in the OP). Recorded a short video, but would not launch from Gallery app. But MX Player played fine (with audio). And the mic with Sound Recorder app did its job. Various MP3's played well (in MX Player, Double Twist, Apollo, and Google Music) and Viper4Android sounded good in limited testing.

Both the GEL launcher and Nova Launcher appears to work well. But more sluggish navigating home screens, the app drawer, and displaying Settings menus, versus CM11-3.0 kernel.

Noticed a vertical column of pixels from left side of screen appearing to the far right. Adjusted dpi to 155, rebooted and that fixed it.

UPDATE. After I wrote this, while an audio track was playing in MX Player, I selected 'Go To Sleep" (from top right menu) and screen went black (as expected) but music track stopped and a strange tone emanated from the speakers. And device would not wake up, so had to push power button for ten seconds to reboot.

After auto rebooting to the lock screen I let the device go to sleep, and it auto rebooted on its own. Then this time after booting to the lock screen, and going to sleep, the device shut down. And had to press Power+Home for 30 seconds to get device to boot.

Is this a known issue with this ROM of this specific nightly? Never observed such spontaneous shutdowns on the CM11-3.0 kernel. Any recommends to avoid?

I unchecked Screen Off Animation (in Display > Settings) to see if that might be contribution to the sleep issue, but sleep crash problem continues unabated.

I reset the device to go to sleep at five minutes. And plugged into wall charger, and device appeared to be charging fine. But then at five minutes the device went to sleep and locked up again.

These last few "sleep tests" were with both WIFI and Bluetooth off and no apps running ( I did not look at the task list to see what might have been running in the background).

Besides these crazy SOD's when device goes to sleep, or when I turn the screen off, everything else I've checked so far is good.

Would like to check sleep drain and observe recharge characteristics but can't until I find a solution to the the sleep SOD issue (the device even goes to sleep which results in a SOD, even while charging).

Rather than keep the screen on all the time decided to restore my CM11-3.0kernel nandroid to charge up and give me time to read through this thread in hope for a solution.

Does this still apply?
