Created an attachment (id=71072)
 --> (https://bugzilla.kernel.org/attachment.cgi?id=71072)
usbonoff-with-mount.sh - script to reproduce the crash

For the record, it is very easy to reproduce the bug with the attached script,
which repeatedly mounts, forces an eject, then umounts the USB device until the
kernel eventually crashes. The procedure is:

1. Create a VirtualBox VM running Ubuntu 11.04 64-bit with the kernel being
tested and boot the VM in recovery mode, ie so no desktop is running.

2. Use the VirtualBox USB facility (right click on the USB icon in the status
bar) to attach an ext3/4 drive to the VM.

3. Run the attached script, specifying the target USB device as the argument
(the script lists possible devices if you don't supply an argument). There's a
commented-out option to redirect output to output to an external machine via
netconsole as well, ie to capture the crash log, which you can't fully see in
the VM window.
