>Description:
Typing "ipf -E; ipf -D; ipf -E; ipf -D" usually causes a kernel panic.
Commands were typed as root.

These messages are displayed:
pfil_list_remove:  no function on list
panic: pfil_list_remove
Stopped in ipf at         _Debugger+0x4:  leave

Once it seemed to not cause a panic, but typing the commands on
separate lines still caused the problem.  (However, I could be
confused - the non-panicky behavior could not be reproduced. ;-)

>How-To-Repeat:
Type "ipf -E; ipf -D; ipf -E; ipf -D" as root and it should panic.
At least on my machine, this works just about every time.
