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:
