>Description:
when i use ipfw pipe and queue - it works but i'm getting a lot of "OUCH! pipe should be idle." and after a while system crashes on amd64.

i googled and found about changing type of numbytes in structure dn_pipe in ip_dummynet.h, but it's already changed in 8.0-RELEASE-p1

It's really a problem for me i had to downgrade to 7.2 to be able to use it.
It's important feature to me. Worked perfect in 7.2
>How-To-Repeat:
use pipes and queues with ipfw
>Fix:
no idea
