6addb1d6de1968b84852f54561cc9a999909b5a9
appear to be relevant. Apply to your kernel and see if it helps...
Looks as if I have to start using git ... I always feared that this day will come. ;-)

If I'm able to reproduce the oops with my patched kernel, I will gladly follow your advice.

AFAICS, lkml.org/lkml/2007/7/24/20 is the same patch...

Ok! It happened again....

I was able to reproduce the Oops twice. Once with my patched kernel
(2.6.23.12 patched with tuxonice-3.0-rc3-for-2.6.23.9 on Debian
stable/testing/unstable) and the second time with a vanilla 2.6.23.12
kernel. So this isn't related to Tuxonice.

The only method to reproduce the oops was to disconnect the Wacom Bamboo
tablet. So I think that my memory was failing me, when I wrote in my
original message that I haven't disconnected the tablet. Sorry about that!

The tablet is connected via a Belkin hub. All I've modified in the system to make the tablet work was to build a new xorg driver with the source from linuxwacom-0.7.9-4 (http://linuxwacom.sourceforge.net/) via
'configure/make/make install'. And I modified xorg.conf of course.

I've CC'ed everybody who has already been involved in this thread or who
I have been asked to CC. I will try to give every information avaliable,
even if I've already posted parts of it in an earlier message, to make
sure everybody has the pieces he needs.

So here's the code for the vanilla kernel:
