Thanks Milan I believe you are right about it being a bug. I was able to
trigger the panic with the script provided and the results are very similar
(although I'm now having a hard time recreating my problem on demand).

I should have fun finding this kernel for SLES10 SP4 even though the minor
is only 2 off...

Thanks again for everyone's help.
