I've been having all the usual issues since the ICS update and the 1.21 update has made things better. I even went 126 hours without a random reboot before having to restart it due to the screen not responding correctly (stuck on homescreen, unable to select anything). But I just noticed that my screen would turn off after only a few seconds. It is set to turn off after 5 min. SO I went to check on status, and the up timer was running minutes as seconds, and seconds as 100th's of a second... I clicked to see if there was an update and the little spinner was going around super fast... It looks like the tablet was running at 60-100x speed on everything!
