I haven't been able to reproduce the freeze yet. Ran the tablet on rom2sd for more than an hour with all kinds of apps, Netflix, Quadrant etc - works like a charm.
I did format the ext4 partitions before installing rom2sd (yet again). Maybe I finally got it right?

Ok, got adb up and running. The full logcat is attached. I used the most verbose logging and the last responsive thing I was able to do was go into settings and attempt to keep wifi on in the low power settings (this occurs at 11:12:34.489 in the log). The tablet obviously saves this setting however the screen fails to update or register input after this point and actually continues to highlight the check box for that setting option as if I was continually touching it. I let the tablet run for a while to see if it was just laggy, but it failed to respond for over ten minutes... Anyways, let me know what you think and I'll be happy to test any theories.
(as a side note, you'll probably notice my wifi continually disconnecting and reconnecting, but my tablet has done that since I purchased it so it's probably unrelated).
