FC2T3 - LVM with RAID1 Failure

[Brian Hanks]

Two attempts to install FC2T3 with LVM2 on top of RAID1 have both ended
in the same failure.  This is the same disk layout that I've used
successfully in previous RH9, FC1, and FC2 installations.  

The boot process dies right after it attempts to enable RAID.  The error
is:

kernel BUG at drivers/block/cfq_iosched.c:404!

{trace info}

drivers/block/ll_rw_blk.c:1156:  spin_lock(drivers/ide/ide.c:02347988)
already locked by drivers/block/ll_rw_blk.c/2164

Any thoughts?

Thanks,
-Brian
