Panic with VIMAGE and pf

I was trying to enable VIMAGE (for use with jails) but stumbled upon the
following panic:

Fatal trap 12: page fault while in kernel mode
fault virtual address: 0x28
current proceess = 38 (pfctl)

db> bt
pfil_head_get() at +0x41
pfioctl() at +0x11f2
devfs_ioctl_f() at +0x77
kern_ioctl() at +0xf6
ioctl() at +0xf0
syscall() +0x137

I can easily reproduce this in single user mode using:
# kldload pf
# pfctl -f /etc/pf.conf

I disabled VIMAGE and the panic didn't occur anymore.

I'm running amd64 stable/8; r206458. (I also tried this 3 weeks ago; but
had the same problem)

I'm not able to get a dump; the memory dump-thing stalls after printing
the first mark.
