Interesting.  So, it's just me then (which is why there haven't
been any panic reports from me for a while).  There's heavy use of
the following modules to the tune of 3*10^9 packets a day peaking
at several 1000Mbits/s:

Id Refs Address            Size     Name
 1   10 0xffffffff80100000 6f3108   kernel
 2    1 0xffffffff80a22000 4986     if_lagg.ko
 3    1 0xffffffff80a27000 9f9      pflog.ko
 4    1 0xffffffff80a28000 5292     if_bridge.ko
 5    1 0xffffffff80a2e000 350f     bridgestp.ko

I suspect it's blowing up in there somewhere a few times a week.
I'll try compiling them into the kernel and see if that yields
a useable vmcore.
