Performed the usual src update in head/amd64; today was from r325137 to
r325228. Laptop had no complaints; everything Just Worked (as usual).
This time, it was the build machine that whined -- rather less
inconvenient for me. :-} Here's what it says currently:

Links to yesterday's verbose dmesg.boot for this machine ("freebeast")
-- as well as a log showing the uname string for each daily update,
among other things -- may be found at
<http://www.catwhisker.org/~david/FreeBSD/history/>.
This particular panic appears to be quite reproducible.
Any suggestions for diagnosing or fixing it? (I can leave the
machine in this state for a while: normally, after successfully
smoke-testing head, the machine is powered down until 23:50 local,
when it comes back up (in stable/11) and starts re-syncing its local
private SVN mirrors.)
Thanks! :-)
Peace,
david
