At December 27, I met the similar problem.  The system caused a panic.
Usually, the system reboots but the system was halted at that time.
The console shows as follows:
============================================================

stack pointer           = 0x28:0xe5c38c2c

code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 42 (fw0_taskq)
trap number             = 12

current process         = 3 (g_up)
trap number             = 12
============================================================
At the time, I did not set up for the crash dump.
Now, I added the setup to rc.conf to make a crash dump.


The following is the part of start up message that may relate to the problem.
