    Andrew, how about I give you a leaf account so you can upload these
    crash dumps & kernel.debug's so I can take a look at them?

    There are only two possibilities that I can think of:  (1) Either you
    are running something that is triggering the problem that we aren't
    or (2) You've got buggy hardware.

    Lets assume (1) for the moment.  The kernel config you sent me on the
    5th has some interesting possibilities.  Things you are doing that most
    of us aren't:

    makeoptions     DEBUG=-gstabs
    options         INET6                   #IPv6 communications protocols
    options         IPSEC                   #IP security
    options         IPSEC_DEBUG             #debug for IP security
    options         UDF
    options         PQ_CACHESIZE=512
    options         NETGRAPH
    options         CPU_ATHLON_SSE_HACK
    options         PCI_ENABLE_IO_MODES
    options         SC_PIXEL_MODE
    pseudo-device   splash
    options         IPFIREWALL              #firewall
    options         IPFIREWALL_VERBOSE      #print information about
    options         IPFIREWALL_FORWARD      #enable transparent proxy support
    options         IPFIREWALL_VERBOSE_LIMIT=100    #limit verbosity
    options         IPFIREWALL_DEFAULT_TO_ACCEPT    #allow everything by default
    options         IPV6FIREWALL            #firewall for IPv6
    options         IPV6FIREWALL_VERBOSE
    options         IPV6FIREWALL_VERBOSE_LIMIT=100
    options         IPDIVERT                #divert sockets
    options         IPSTEALTH               #support for stealth forwarding
    options         RANDOM_IP_ID
    options         SMBFS                   #SMB/CIFS filesystem

    We need to narrow down the issues as much as possible.  Get rid of all
    options that you don't need.  IPV6, IPSEC, and SMBFS are particular
    possibilities.  Virtually no testing has been done on any of them.  But
    get rid of everything you don't absolutely need and even get rid of
    things you do need :-).

    In fact, the more I look at your configuration, the more I believe
    that the bug is to be found somewhere in one of those options.
