Hello,

I have a recent oopps on a small file server I have running.  The
machine in question is a dual, dual core AMD Opteron 2.2GHz w/4G RAM,
3Ware 9650SE (14 drive RAID 10), using XFS, LVM2 (latest), exported
via knfsd.  Kernel is 2.6.21-rc4 64b.  Here is the bt:

Once this oops happens, the machine is still usable, however NFS
crawls to a halt (in fact one of the machines with a mount point of
this machine, failed to respond anymore - I assume that thread is the
one that ooops'ed).

Any more information or debugging, please let me know.

TIA!
Phy
