Was it mounted at the time? (either manually, or by HAL)

The same Oops with 2.6.10-rc1, seems to work fine with 2.6.10-rc1-bk14
(tried multiple plug in/outs in a row). However hal in FC3 doesn't
work with 2.6.10-rc1-bk14, it will not recognize USB devices :(

Hm, scsi bug, not a usb-storage bug.

Comment 9 Jason Baron 2004-12-02 23:09:46 UTC
Can you re-test this with the latest rhel4 kernel at: 


Comment 14 Andre Robatino 2004-12-13 21:44:44 UTC
  My father has almost the same problem, except that it seems to only
happen with the latest (681) kernel, and not 678 or earlier.  Also,
the Oops happens upon shutdown, not immediately upon removing the USB
device.  If the device is left attached until after shutdown, the Oops
doesn't happen.  Below is a system log attachment.  The device is
pulled at 14:07:31, and then the shutdown is started at 14:07:36, when
the Oops happens.  The machine hangs, and at 14:08:09 a Ctrl-Alt-Del
successfully reboots the machine (sometimes the machine is totally
hung and this doesn't work).  His machine is FC3 with all standard
updates applied.

Oops from system log

Comment 16 Antti Andreimann 2004-12-19 01:16:00 UTC
Still had issues with older releases, but the latest RHEL4 test kernel
(2.6.9-1.906_EL) works like a charm. Thank You davej! Running on it
right now.
