I can reliably reproduce this same panic on yesterday's current running
on an Acer Ferrari 3400 by starting the build of procmail.

I'm not sure if this is related to the file locking tests that procmail
runs while the port is building, but it always triggers a panic.  I
didn't manage to get a backtrace, because the system instantly rebooted
both times I tried to install procmail, but if necessary I'll try to get
a dump.
