Hi Guys,
Haven't had time to look at it for a couple of days but as far as I can
see usb is mainly merged in 2.4.13pre2 andd has another usb-uhci bug
fixed but no luck. included is the processed oops and some info from
dmesg up to the unprocessed oops - i found the unable to handle kernel
paging request interesting rigght before the oops. Anyway here it is for
you info.
Regards
Peter
