kernel panic, x86, 2.7.3.859.ge5104

[Matthew Dillon]

    I've pushed a bunch of work, please update to the latest master
    and continue testing!

    No smoking gun but I suspect machine load may be causing m_reclaim()
    to get run, which drains various protocol caches.  Those caches were
    not MPSAFE.  The changes address that issue.

    If these changes don't fix the problem then compile a fresh kernel
    with two options added to your kernel config:

    options         SOCKBUF_DEBUG
    options         MBUF_DEBUG

    These are fairly invasive options so only compile them in if the
    problems have not gone away.  Hopefully then we will get a panic
    closer to where the actual bad code is instead of well after the
    fact.
