Bug #3061: HAMMER2. Hang up, reboot, and crash.
http://bugs.dragonflybsd.org/issues/3061

* Author: yellowrabbit2010

----------------------------------------
I started the build as
------
nice -n 9 make -j 8 buildworld
------

@USR-SRC is mounted at /usr/scr, @USR-OBJ is mounted at /usr/obj.
The compilation stalled, I pressed reset and after reboot the system dumped immediately. 
After that I was able to boot, but the PFSes were gone.

Each attempt to mount any of them led to the following errors:
