After a CVS update late last night (4 May 2003) and rebuild/install of 
world, we've got a box that exhibits the exact same problem.  Our box's 
layout includes two UFS1 partitions (one is the root), and a Vinum RAID 
1 UFS2 parition for /usr.  (The other UFS1 partition is a mirror of the 
root partition on another drive.)

Manual attempts to mount root also fail with error 22.

Any ideas what's up?

Wondering,
Aaron out.
