Yes, I simplified my running config just for testing in following regard:

1) I've disabled pf module, here is what I've managed go get just before crash
(sorry, linux alias):

moonfall ~ # lsmod 
Id Refs Address                Size Name
 1   51 0xffffffff80200000  1f18f80 kernel
 2    1 0xffffffff82119000   6724a0 zfs.ko
 3    2 0xffffffff8278c000    4eaf0 ipfw.ko
 4    1 0xffffffff827db000     8ba8 ipfw_nat.ko
 5    2 0xffffffff827e4000    176a8 libalias.ko
 6    1 0xffffffff827fc000     4240 coretemp.ko
 7    1 0xffffffff82b20000     3378 acpi_wmi.ko
 8    1 0xffffffff82b24000     3250 ichsmb.ko
 9    1 0xffffffff82b28000     2180 smbus.ko
10    1 0xffffffff82b2b000     7638 if_bridge.ko
11    1 0xffffffff82b33000     50d8 bridgestp.ko
12    1 0xffffffff82b39000    378f8 linux.ko
13    2 0xffffffff82b71000     db70 linux_common.ko
14    1 0xffffffff82b7f000    30ac8 linux64.ko
15    1 0xffffffff82bb0000     2260 pty.ko
16    1 0xffffffff82c00000   53f420 vmm.ko
17    1 0xffffffff82bb3000     21cc nmdm.ko

2) The only (mandatory) rules in config at the moment of testing that should
have been loaded was:

00009     2        0 deny ip from any to any MAC any 02:00:00:00:00:00/8 layer2
via em0
65534 62027 22596555 allow ip from any to any
65535    13      320 allow ip from any to any
