    I don't think that's going to be very helpful.  It's got to be a kernel
    issue somewhere but without a kernel panic or kernel dump we're kinda 
    stuck figuring out what the cause is.

    I think your best bet is to continue to try to get a dump.  If you have
    this option enabled in your kernel config:

    options         ALT_BREAK_TO_DEBUGGER   # CR ~ ^B

    Then it should be possible to use the CR + ~ + CTRL-B sequence
    on a serial console to break into ddb and then panic the system, and
    hopefully this would work even after the system has nominally locked
    up.  Doing a 'sysctl kern.sync_on_panic=0' might also improve your
    chances of getting a successful dump.

    (assuming that you've got sufficient configured swap and setup the
    dump device).
