Description Erwan Martin 2011-09-28 10:30:16 UTC 
When using a VIMAGE kernel with pf, stopping a jail creates a panic.

panic: Assertion lock == sq->sq_lock failed at /usr/src/sys/kern/subr_sleepqueue.c:335
cpuid = 0
KDB: enter: panic
[ thread pid 1026 tid 100064 ]
Stopped at      kdb_enter+0x3a: movl    $0,kdb_why

How-To-Repeat: Compile a VIMAGE+pf kernel.
Start pf.
Create and start a jail.
Stop the jail.
