Your issue isn't obviously directly related to mine. mps is a CAM driver
and aac is not (at least not for normal block volumes), which makes disk
probe/attach quite different.  I also don't see an obvious driver flag
like the one in aac.

Do you see GEOM error messages like "Opened disk aacd0 -> 6"?  When you
get a failed boot, if you type '?' at the mountroot prompt, do you see
the base device (ie "da0"), but not partitions/slices ("da0s1",
"da0p1")?  If both of those are true, then your problem might be similar
to mine.
