This entry is being used for tracking a regression from 3.0. Please don't
close it until the problem is fixed in the mainline.
All USB bugs should be sent to the email@example.com mailing
list, and not entered into bugzilla. Please bring this issue up there,
if it is still a problem in the latest kernel release.
reopening and reassigning to the correct developers.
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?
