[OpenAFS-devel] OpenAFS on SGI's SLES9-SP4 oopses upon loading

[Alf Wachsmann]

Hi,

I just upgraded our SGI Altix system to the latest patchset,
Suse Enterprise Linux 4 Service Pack 4 (it was running SP3 before)
and I now get an oops when loading the OpenAFS kernel module.
This happens with OpenAFS 1.4.5 and also 1.4.7.rc1.

oops output and kdb's backtrace is below.

Is there a fix for this?

Many thanks,
                   Alf.
