It seems like a corruption issue. The machine is sometimes usable for
short periods after this errors occurs, but is otherwise deadlocked.
I did go back to 3.19.0-4.4, and the problem is persisting. I also tried
building a kernel from Linus' git tree and the problem is still there.
My guess is that something changed outside of the kernel that is now
triggering this bug. Perhaps it was the switch to systemd, or perhaps it
is that I have a juju local provider deployment going on this system now
- or a combination of the two.
** Changed in: linux (Ubuntu)
