I read all the posts about the random reboots, and seemed to me it happens when the TF goes on deep-sleep mode. So I added these 2 lines to my build.prop and have not gotten anymore reboots:

ro.ril.disable.power.collapse=1
pm.sleep_mode=2

If someone can try it, and post your results to verify, it could help others that are having this issue.

Thanks for the suggestion. It has been how long since you add the 2 lines? My first reboot and the second one has a gap of more than 48 hours.

What is the effect of that mod on battery life?

No, I just thought that since some of the reports were mentioning the Deep-Sleep state, then disabling this could solve the problem. So I decided to root and modify the build.prop by adding those two lines. I haven't had a single reboot in more than 48 hours now. Before the modification I would get a reboot every 8-12 hours.

I didn't see much of a change in battery life. Try the mod and see how it goes for you.

Added end rebooted. Experienced only a few reboots in the past 5 days. Wiped data from HC Revolver 3.11.1 and flashed ICS last week.

Will report. The first command line sounds promising already. I don't know zilch about coding so excuse me from being nub, but shouldn't that 0 be changed in 1 because the disable function should be 'enabled' (assuming 0= enable and 1= enabled)? Sounds more logical to me.

Good catch, guess I made a mistake when I typed the post. Yes, it should be 1 to disable the Power Collapse.

Ok changed 0 to 1. Did not have a reboot in the past twelve hours, but I had them seldomly anyway. Will report again.

-edit: just had a 1st reboot within an hour of changing from 0 to 1. Happened when I left my appartment (and my wifi connection) and opened my tablet in the train. I have wifi turned of during sleep. I also upgraded YouTube app for testing purposes during that period (although I never use it) to test 720p. Not sure if it's related.
