Ok, great ..
this and similar panics are products of accidental stp loops. I have two
same boxes with the same network setup connected to the same switch. At
one point i've tested bluhm@ and sashan@ diffs and forget that i have
tpmr(4) or veb(4) configured on both boxes, which is loop ...
So now, when i understood what i've done i can easily reproduce panic
with yours and dlg@ diff ... i just start to send traffic over one box
and other box panic :)
all those panics are without pf and with tpmr or veb
here's few panics .. i can send details if you find some panics
interesting ..
