(In reply to Gustavo Romero from comment #9)

Having FreeBSD hang around:

Trying to mount root from ufs:/dev/da0s2a [rw]...

might be tied to the following. . .

Hanging here is something addressed by the
"UMA limit" part of head -r327485 . Bugzilla
224330 has material about it. As I understand
-r326347 is what broke that specific aspect
of things. (It had other issues as well,
and apparently causes some other problem to
show up that was previous hidden.)

As for -r327485:

Log:
 Fix arc after r326347 broke various memory limit queries.  Use UMA features
 rather than kmem arena size to determine available memory.

 Initialize the UMA limit to LONG_MAX to avoid spurious wakeups on boot before
 the real limit is set.

The "arc" reference is a ZFS file system handling issue.
