ffs_mountroot: can't find rootvp

Hi,

today's (Apr 13th) CURRENT can't find the root fs anymore

This happened while updating from Apr. 10th to Apr 13th,
just after 'make installkernel KERNCONF=GENERIC' and
'reboot.'

Here todays messages:

Mount root from ufs:/dev/ad0s1a

Old -current kernel as of Apr 10th works okay though
and can mount all filesystems without problems. I used
the live CD in fixit mode to rename /boot/kernel.old in
/boot/kernel and reboot for now.

When would it be safe to cvsup again? ;-)

Thanks,
-cpghost.
