Odd partition error in F12, but not in F11

I have a friend that doesn't read the list that has been fighting a very
odd issue with F12, which does not surface in F11.
On a clean install from the F12 DVD with the updates repo enabled, he
created a RAID 5 setup across 6 drives. Each drive has only one
partition on it. When the machine reboots it cannot rebuild the raid
because it cannot find 4 of the 6 partitions. It drops to the root
prompt and from there if you do an ls /dev/sd?* four of the drives show
no entries for the partitions while the other two show the normal one
partition. If you open one of the incorrect drives with fdisk it shows
the correct partition table and if you write it out from fdisk it then
shows correctly in /dev
If you do this to each of the drives they all show up and then mdadm can
assemble the raid correctly. Reboot the machine and you are right back
to where you started.
dmesg seems to show the kernel correctly listing each drive and
correctly listing them with each one partition, but the entries are not
in /dev for the partitions.
We rolled back to F11 and performed the same process and it worked fine.
I am really at a loss for what to look at or what to test against. We
currently have the machine up and working with F11, so I can get any
information about hardware that might help.
I posted it here rather than the users list, because I don't really
think this is a configuration problem. It seems like a bug in F12, but
I don't know what to check it against.
