Hi,
I was just playing around with hstest and my new Bluetooth headset (a
Jabra BT250, to be precise) when I got this oops after a few minutes'
playback:
usb 1-1: new full speed USB device using address 3
usb 1-1: USB disconnect, address 3
__tx_submit: hci0 tx submit failed urb cff5a614 type 3 err -19
__tx_submit: hci0 tx submit failed urb cff5a614 type 3 err -19

Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:

hsplay segfaulted, but I was able to start playing again afterwards.
Also, the kernel disconnects and reconnects the device spontaneously
every once in a while while playing (both before and after the oops),
like this:

try it without the --mm1 patch. What does "hciconfig -a" say about your
Bluetooth dongle?
