I've been observing this bug in other kernel versions and other hardware
configurations, so I think it's easily reproductible.

Happens when I/O error on external ide <-> usb drives. Can be reproduced
by unplugging the usb cable while accessing the drive, or with a faulty
drive.

I don't think my real u2w scsi controllers would like the real scsi disks
being hot swapped, so I haven't tried there.

Regards.

It's not, it clearly looks like SCSI trying to kill off the queue
with pending commands.

That's what it looks like to me too ... there should be a fix for this
in the scsi-misc-2.6 tree.

There also was a fix for usb-storage just submitted for the gregkh-2.6 
tree:

http://marc.theaimsgroup.com/?l=linux-usb-devel&m=109744234829347&w=2

It should help prevent the condition that triggers this situation.
