altq kernel panic with recent HEAD


From: Kyle Butt <kylebutt@xxxxxxxxx>
Date: Tue, 10 Oct 2006 11:48:55 -0600

Core and kernel forthcoming to my leaf account.
Happens upon loading pf with altq. Doesn't happen If I comment out
altq. It is repeatable. I can give my pf.conf if that would help.

Here's a backtrace:

Previous frame inner to this frame (corrupt stack?)




Thanks for looking at it,
