update: I'm not quite sure, but I may have found the problem in my case: a bad harddrive. Windows starting freezing as well when accessing a disk I use to share data between Ubuntu and windows. I replaced the drive, and so far Gutsy seems stable. its only been 12 or so hours, so its too early to know for sure, but it looks promising.
