Hmm, this doesn't look like an ext3 problem. The hanging command is waiting for
page to be unlocked which, given it is 'cat' reading a file, is likely because
read command interrupted by device unplug was not properly completed... So I'd
blame either USB or SCSI layer. Or Greg, what made you think it's an ext3 bug?
