RAID resync oops 2.4.19-pre10

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

I'm still try to get my 2TB raid array to resync without oopsing -- since pre10 has new aic7xxx SCSI code I figured I'd try that.
This oops occurred and the kernel was still running.
I've seen this type of NFS oops on numerous previous kernels doing this same resync.
I'll try removing the NFS module again and see what happens.
If ANYBODY has any bright ideas on this it would be much appreciated....I can't test 2.5 because RAID5 won't compile on it.
This situation is repeatable as all get out -- I can move this array to another (slower) box and it will resync just fine.  So I'm
of the opinion that this is a race condition that is only exposed on the much faster box.
