My feeling is along the lines of Carl's in that I think it is a udev
issue.

I had a similar problem to you, Andy, with the 2.6.15 kernel and a
RAID1 setup - it could not find /dev/md3 to mount it (/dev/md3 was the
root partition).  It looked like udev had not yet created the device.

Unfortunately I didn't get to experiment much as the box in question,
whilst not mission-critical, could not be off-line for very long or
people would start whining #;-D 

I just rolled it back to 2.6.12 to get it back up and running.

Ozz.
