Pick an oops...any oops...
Waited for md0 to finish resync....qla2x00 wasn't loaded....no NFS. No
other resyncs going on. Next I'm going to back to an ealier kernel and see
what happens. Now got this oops:
ksymoops 2.4.5 on i686 2.4.19-pre4. Options used
-V (default)
-k /proc/ksyms (default)

OK...no nfs modules loaded now and we get another oops (all 3 raid arrays
were resyncing). Next we will let md0 resync (this always seems to work
OK), disable the fibre chanel (removing the qla2x00 module) before we try
our aic7xxx raid5 resync.
