Bluetooth USB oopses on unplug (2.6.1)

Bluetooth USB oopses on unplug (2.6.1)

[Pavel Machek]

Hi!

In 2.6.1, bluetooth-over-usb (hci_usb) works very well... As long as I
do not unplug it. When I do, it oopses. Is there newer version of
bluetooth that I should try?

try to disable the SCO audio option for the driver itself. It should
work then, because the driver no longer uses ISOC transfers.

However show us the oops (through ksymoops) and show us your USB
hardware on your motherboard (lspci).

I'll have to hand-copy the oops, as machine dies after unplug. Here it
is:

Oops: 2
EIP  is at uhci_remov_pending_qhs
Call trace:
	uhci_irq
	usb_hcd_irq
	handle_irq_event
	do_IRQ
	common_interrupt_1

as I expected. It is an UHCI host adapter and it looks like the uhci_hcd
driver has problems to unlink the ISOC URB's. Look at the LKML and USB
mailing lists for similiar post. At the moment I don't know of any patch
for it. Sorry.

No problem. For the record, it works okay without SCO. Thanks for that.
