Cannot mount root ufs:/dev/ar0s1a Error 22 after update

Hi all,

I updated today three boxes from 5.0R to CURRENT,
and all three boxes, with different disk-layout.

After a reboot, I got on all boxes the same problem:

Cannot mount root ufs:/dev/ar0s1a Error 22 (EINVAL)

or

Cannot mount root ufs:/dev/ad0s1a Error 22 (EINVAL)

I tried to set the root manualy, but no chance. Only
common thing on the boxes are that two have a ATA
Raid (ar0) and one just a normal ata disk.

Mounting /dev/ar0a didn't work too.

I also used ufs2 on one box for all slices, ufs1 on
the two others.

What is involved to get this working again, and why
is it missing in /usr/src/UPDATING ?

Martin
