Subject: Kernel oops with bluetooth usb dongle
Hi,
Since the rc's of 2.6.24, my machine crashes when I try to use the USB dongle.
No other activity seems to create a crash. The system is stable with 2.6.23.1.
It is a Dell Dimension 8400 updated daily to mandriva cooker. I am not
subscribed
to this list, so please CC me if there is any more information I can provide.
Here is the Oops with 2.6.25-rc1:
BUG: unable to handle kernel NULL pointer dereference at 00000000
