I'm sure I've done something wrong with the setup of this machine, but
I'm at a loss to figure out what - so I'm hoping that publically
embarrassing myself will do the trick.  :)

I have a 4.0_BETA2 amd64 system with root on raid1 (raidframe) -
everything seems to work OK _except_ when I fsck the root partition:

** /dev/rraid0a
** File system is already clean
** Last Mounted on /
** Root file system
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups

=2E.. it's always block 64.   I've set up dozens of root-on-raid1 systems=
,
and this is the first time I've run into this.  Could I have gotten some
offset wrong somewhere?

In case it triggers something for someone, here's the output of raidctl
