Help with an "Oops" message

I have a server that is consistently crashing with Oops messages like
the one included here. It is an SMP system, and it seems to be pretty
well split between which processor it happens on. Once we get the oops,
we have to hard reset the system. The "kernel: current->" is *always*
tss.cr3

Regards,

Jon
