What seek errors are these? Can you show me a log?

This doesn't prevent a partition scan; it just prevents the mknod
in /dev .

You can't -- but that shouldn't be a problem. When it creates the raid
device, it removes the partition devices from the original disks. Is
that not happening for you?

There's nothing in mkblkdevs that performs any device access at all, so
that's probably not it. At that point the kernel has already scanned
the partition table, exactly as it had in FC4. So you're probably
seeing something after that.
My first guess is that we're getting the parameters for your dmraid
device wrong, and then the errors come from scanning the partitions on
that, but I can't be sure without more info on how your disks are set
