kernel-smp-2.6.10-1.741_FC3 dies during boot, unable to read superblock on ext3 filesystem

[Anne & Lynn Wheeler]

have gotten smp kernel 741 to boot on smp machine with scsi drives and 
standard ext3 boot filesystem.

smp kernel 724 & 741 fail to boot (error message saying unable to read 
superblock) on smp machine with pair of sata drivers configured with 
logical volume support (fresh fc3 install) where all the filesystems are 
ext3, the boot filesystem is (software) mirrored on the two drives and 
the remaining filesystems are (software) striped on the two drives. smp 
kernel 681 works fine.
