Everything was working great using CM10.2 until a few days ago when my TF700 became unresponsive after 5-10 minutes whenever I was running on the SD card mounted ROM. (It had been working fine for about a week of steady use). When it becomes unresponsive, it doesn't register any screen touches nor do any hardware keys work. The only way to recover is with a hard reset (holding the power button for a while even though pressing once has no effect). Decided to see if it was something related to CM10.2 so I reformatted the SD card and installed CROMI-X to the SD card using the CROMI-X installer... used it for a little bit and got the same problem.
I'm back to using the internal ROM and have no issues.
Has anyone else experienced this? Could it be a problem with the SD card itself (I'm using gparted to format and the card appears to function normally in other devices...)? I don't think it's a kernel issue as I'm using _that-v7 both internally and on the SD ROM (either through the CROMI-X installer or with the modified rom2sd2.zip from _that's dual boot thread).
Anyways, any advice or theories would be appreciated. I'd post in the original dual-boot thread but as a serial lurker/flasher I don't have enough posts to participate in the dev thread.
