No INET6. My kernel is pretty basic.

The kernel has witness and invariants. The DDB trace shows:

Tracing pid 159 tid 100047 td 0xc1592340
kdb_enter(c066578d,100,0,0,0) at kdb_enter+0x2c
panic(c0680600,c068096e,d4047010,0,0) at panic+0x10s
syscall(c1564cc00,c15c3680,c1564d00,c0709c40,c06c18c4) at syscall

Process 159 is ifconfig.

I have GDB in the kernel, but haven't connected a serial console to this
machine before, so I'll need to hunt around for a cable and finish the
upgrade of my desktop machine which I decided to clean and re-install
all ports on yesterday. Bugger.
