Hi,

I have several hosts running FreeBSD/amd64 7.2-STABLE updated on 11.01.2010
and 25.02.2010. Hosts process about 10K input and 10K output packets/s
without issues. One of them, however, is loaded more than others, so it
processes 20K/20K packets/s.

Recently, I have upgraded one host to 7.3-STABLE, 24.08.2010.
Then bge on this host hung two times. I was able to restart it from
console using:
  /etc/rc.d/netif restart bge0

Then I have upgraded the most loaded (20K/20K) host to 7.3-STABLE, 07.09.2010.
After reboot bge hung every several seconds. I was able to restart it,
but bge hung again after several seconds.

Then I have downgraded this host to 7.3-STABLE, 14.08.2010, since there
were several if_bge.c commits on 15.08.2010. The same hangs.
Then I have downgraded this host to 7.3-STABLE, 17.03.2010, before
the first if_bge.c commit after 25.02.2010. Now it runs without hangs.

The hosts are amd64 dual core SMP with 4G machines. bge information:

bge0@pci0:4:0:0:        class=0x020000 card=0x165914e4 chip=0x165914e4 rev=0x11 hdr=0x00
