Hello! I have problems with ip_mroute (loaded as module) - kernel
multicast packet forwarder.
I have 2 disk: freebsd 8.2 release amd64 on first and freebsd 9.0 rc1 on second.
I use net/igmpproxy to watch IPTV on my home atom-based router.

On FreeBSD 8.2 it works good.

But when I try to use FreeBSD 9.0 RC-1 in same role (with same
configs, of cource) I have messages like:
Nov  7 16:16:46 timp igmpproxy[35495]: received packet from
172.16.254.1 shorter (28 bytes) than hdr+data length (20+28)
Nov  7 16:16:47 timp igmpproxy[35495]: received packet from
172.16.254.1 shorter (32 bytes) than hdr+data length (24+32)
Nov  7 16:17:28 timp igmpproxy[35495]: received packet from 10.85.13.5
shorter (28 bytes) than hdr+data length (20+28)
And IPTV doesn't work =(

Any ideas?
Do you need configs?
