Lock Order Reversal on 7.0-STABLE with pf and ipfw / dummynet (extra details)

[Alex Popa]

Extra details:  The machine shows no problems when running
6.2-RELEASE-p7 / i386.

Upgrading to 6.3-RELEASE / i386 caused the machine to start randomly
locking up, much faster than 7.0 (about 4 hours versus 12+)

Have tried 7.0-RELEASE/i386, 7.0-RELEASE/amd64, both with SMP support.
I've also tried 7.0-RELEASE/i386 without SMP support.  All of them
exhibited the lockups (amd64 with SMP locked up after most time, the
others were much faster to lock up but this isn't statistically proven).
