Me three!

I got bit by this problem when I tried to do some browsing on my
Thinkpad R40 after my primary (4.10-STABLE) machine lost a disk.

It's a July 5th kernel with SCHED_ULE, DDB, INVARIANTS, WITNESS, and
ACPI.

I couldn't switch to a serial console because the other end of the
serial cable connects to the dead machine.
