Kernel OOPS

[Dan Rich <drich@employees.org>]

I'm seeing the following crash on my server.  This system is a SMP system
with a Highpoint IDE Raid controller and a Buslogic SCSI card (I'm
mentioning that because the crash appears to go away if I remove the SCSI
interface).  From the output of ksymoops, it appears to be crashing in the
xfs routines.
