Recently I've started observing issues like this too. For example, today
I did:

 - run 'fsck -y' twice in single user mode (because actually I was forced to do
   that because last time I hard reset the box)
 - start building stuff with poudriere
 - after approx. 40-45 minutes I get this panic.

Backtrace snippet is the following:
