[Eee Pad Transformer Q&A, Help & Troubleshooting] pursleyt:
Problem Reproduction:

1. Boot the device.

2. No problems during normal usage or when charging.

3. Let the device go to sleep for a couple 2-4 hours

SOD:

When pressing the power button after opening the lid the screen turn on but instead is a black screen, device still seems operational, but screen does not come on, only happened two times since flashing and randomly with nothing I can pin-point it to have a theory from some research, but do not know if it is related.

RR:

Device not reboot unless reboot is initiated, TF101 is rebooting randomly during deep sleeps.

Neither RR or Deep Sleeps occur when the tablet is charging or in active use.

Specifics

Tablet: TF101 Tab and Dock, 16 GB WIFI

Recovery: TWRP 2.3.2.3

ROM: EOS 4 Nightlies Build 99

Kernel: KatKernel_96_JB4.2_Lidpatch

Specific Customization Apps:

K.A.T_V1.2.7 - using KAT Audio, KAT Media Service, GPS fix installed, and adblock hosts file in place.

SetCPU - Profile 1 (screen-on priority 50): Overclocked to 1504Mhz with Smartassv2 govenor, min setting 312 MHZ (read some people do this prevent SOD and RR for the min setting)I/0 Scheduler SIO (also read on XDA others have been very stable with this setup). Profile 2 (Battery less than 38%, priority 75): Stock Max to 312 Mhz Min with conservative governor and SIO scheduler.

**Note: All SOD and RR have occured while SetCPU is in profile 1.

Ram Manager Pro: Minfree setting set to More RAM for devices with over 512MB Memory. JV Heap set to 64MB

Lux Dash: Used to fix auto-brightness setting being too low on transformers. Have it set to dynamic update brightness.

Other settings

Disabled Hotword detection for Google Now fix.

Removed test keys from build.prop and renamed SuperSU to SU in system/apps to get around the Root checks of the TimeWarnerCable live streaming app.

Background: My transformer was in on stock ICS OTA update and was so slow it was barely usable and used battery like crazy. I followed all the procedures on XDA (http://xdaforums.com/showthread.php?t=2063406) and http://public.timduru.org/Android/tf101/eos4/ for wiping, i wiped and formated everything (dalvick, cache, system, factory)besides the externalSD card. Flashed the 99 nightly build and was impressed with how smooth everything was, was like a brand new tab. Did some bench marking and saw the good reviews on KAT kernel, so I flashed KAT kernel and installed KAT app and was even more impressed with performance, benchmarks jumped significantly. Tested everything I could think possible and did not see any major bugs so I figured this would be a good settling point. I did not re-install any of my apps from the Titanium or My Backup Pro or system settings, i installed everything from the market and configured systems settings, after I stopped all the update activities that when I noticed the SOD and RR issues (due to android assistant showing startup times when I had not initiated a reboot). Two days or so ago I installed Reboot Logger to keep track of the RRs. I noticed one SOD on the 18th after 2 hours of inactivity and one on the 19th around the same amount of time of inactivity. There was four RRs on the 19th and two on the 20th. Last night I was doing some digging and saw a bunch of feedback for JB on disabling the location services in setting and app settings, so I implemented that last night as well as removed the dock SD card after before leaving the device in a state of inactivity. After those two changes there was only two RR vs the four the prior day (Although if this is a semi-fix it is a pain not being able to use auto-location for apps) and no SODs again YET.

Let me just say that I love the ROM and KAT Kernel and KAT app, I am extremely impressed with all of it with the way to performs and how buttery smooth it is compared to stock. Lots of Kudos to the developers. If possible I would like to leave KAT Kernel in place because of the performance benefits. If I could get eliminate or minimize the SOD and RRs to an extreme minimum this would be a perfect/Rock solid solution. Attached are the Kmsg and logcats before the last RR and a screenshot of the RR from the Reboot Logger (note the RR/soft boots do not have a restart timstamp next to them, the ones that do are initiated reboots. .

Do you think the latest preview (175) or nightly 100 help the SODs or RRs? Also since the previews are compiled in Linaro and this is the native format for the TF101 be slightly more stable (I did a lot of digging on XDA but could not find a lot one way or the other to justify one direction or another), any empirical data from testing? Just curious. Thanks
