Running FreeBSD on M.2 SSD

[Mike Karels]

Mario, have you ruled out the possibility that the UFS and ZFS filesystems
are overlapping?  It would be worth a careful check of the partition table
and filesystem sizes.  You can check the actual UFS size with dumpfs.
I ask in part because UFS has a tendency to write to the last cylinder
group.

Also, are you sure you want to use both UFS and ZFS?  I do it personally
for historical reasons, but on a larger machine with several disks.  But
there are reasons not to use both, including different memory cache
strategies.
