I hit a very similar problem with a new install last Friday:

https://www.redhat.com/archives/fedora-test-list/2008-February/msg00013.html

Kernel autodetection is gone & the commands in the initramfs weren't
starting the array containing my root VG.

I wasn't sure if this was a bug in mkinitrd/anaconda (for failing to put
a workable mdadm.conf in the image), or a problem with mdadm - none of
the --assemble/--scan options would start the array without my listing
the UUIDs.

Regards,
Bryn.
