Hello,
Attached is a decoded oops from a vanilla-2.2.18 kernel with
a third-party FDDI driver module from Compushack, Germany.
I'm not sure if the bug is in the kernel or in the module,
so I've cc'd the report to both the kernel network people and
the Compushack maintainer (M. Tross), to have a look at.
Compushack driver is csfddi v2.1.11 b25, compiled on kernel v2.2.18.
Regards
-Udo.
