I get this one:

GEOM: ad0s1: geometry does not match label (15h,63s != 16h,63s).
Trying to mount root from ufs:/dev/ad0s1a

The problem is it doesnt happens always, but with soft reset there is
(perceived)
bigger chance to happen. Also kernel without WITNESS and other debug
options have much bigger
chance for this error to happen.
