2.4.17-pre7 oops

["Mike Black" <mblack@csihq.com>]

I've been having problems resyncing my 2TB RAID5 Ultra160 array for every
kernel version I've tried.  Here's the latest.
The drive being resynced is mounted and exported via NFS while it's
resyncing.
I'll try it one more time while it's not exported.

md6 : active raid5 sdm1[12] sdb1[1] sdl1[11] sdk1[10] sdj1[9] sdi1[8]
sdh1[7] sdg1[6] sdf1[5] sde1[4] sdd1[3] sdc1[2]
      1950225024 blocks level 5, 128k chunk, algorithm 2 [12/11]
[_UUUUUUUUUUU]
      [>....................]  recovery =  2.7% (4919104/177293184)
finish=2569.6min speed=1117K/sec

Once the oops occurs on the raid resync thread I end up having to do a hard
reboot
