Hello lkml!

You'll find the kernel config attached:
Steps to reproduce the problem:
1) Insert the usb bt dongle
2) Start the bluetooth services (rfcomm, hcid...)
3) Stop the bluetooth services
4) Extrach the dongle - Doing rmmod uhci_hcd also causes the same oops.
Notice that SCO BT support is NOT compiled into the kernel, so this is a
different oops than similar ones reported before.
After step 3 it is possible to remove rfcomm and l2cap, but hci_usb and
bluetooth seem to lock one another, making it impossible to remove them from
the running kernel.
Regards,
Silla

this looks like another unlink-during-submit bug in the uhci-hcd host
driver. With the latest 2.6.4-bk2 the ohci-hcd is now free from it and
an unplug works again without any oops or freezes. Post your oops to the
USB developer mailing list.
Regards
Marcel
