oops on checking for changes of usb input devices

[Soeren Sonnenburg]

Hi!

When I attach a ps2 mouse and keyboard through a ps2->usb adapter and
then do a rescan for changes in input devices I keep getting this oops.
This is kernel 2.6.7-rc2 on powerbook G4. A way to trigger this is to
reload/restart pbbuttonsd.

Any ideas ?
