2.4.17 Oops on raidstart

[Sven Heinicke]

My vanilla 2.4.17 kernel was oopsing during boot, even into single
user mode.  As I have been having raid issues recently I suspected the
RAID first.  So, I booted from a rescue disk, removed mounted raid
partitions from /etc/fstab (all of which are reiserfs), and moved my
raidtab file out of the way.

During normal reboot, no oops.  I copied my raidtab file back and
issued the raidstart command on md0.  A rebuild starts on my md0 and a
few minutes later I got the included oops.  This is a RAID5 partition
that has given me no problems until now.
