:Hi!
:
:We've got already two hard lockups after upgrading our production
:server from 4.5-STABLE to 4.7-STABLE on November 2nd.  The server
:was rock-stable before, with the uptime more than 90 days.  The
:hardware in question did not change, nor did the kernel config.
:Today's morning I found the system frozen again.
:
:Below is the ps(1) output from the hands-made panic's dump.  There
:are a few processes waiting on either vmwait or wdrain which seems
:suspicious; is there anything else I can do to diagnose the cause
:of the problem?
:..

    I'm hopping on a plane in 30 minutes but if the problem isn't
    figured out by the time I get back (next week), be sure you
    save a kernel.debug and related vmcore and I'll take a look at it.

						-Matt
