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
