I've experienced the same proble with my Motorola A780 phone using usbnet mode
(recognized as a zaurus).
I reported the bug here http://qa.mandriva.com/show_bug.cgi?id=30489 which can
be marked as duplicate of this bug IMHO.

description: 
I have a Logitech wireless mouse with a USB receiver. Whenever this receiver disconnects from the USB controller (either because of its normal sleep behavior or because I unplug it), a kernel oops error occurs:

BUG: unable to handle kernel NULL pointer dereference at virtual address ..
BUG: unable to handle kernel paging request at virtual address ..

These events have variously occurred in the midst of the hald, udevd, and syslogd processes; when the former two daemons were affected by the error, my machine crashed.

I never observed this behavior when using Mandriva 2007.0 on the exact same machine with the same mouse equipment. I was running kernel-2.6.17.8mdv at the time.
