Hi,
the panic which belongs to the attached backtrace
occured during a normal shutdown.
Maybe it might be related to the fact that some time (two hours) before
a USB-Disk where inserted and later on ejected.
Any clues? Some left over stale pointers?
The machine where my IBM A30p Notebook, btw.

Bye!
