Strange Ethernet collisions/frame problem

[Henrique Almeida <almeida@triang.com.br>]

Hi list!

Sometime after upgrading do 2.0 beta I started to have some strange
problems on my gateway machine. This condition can be described as a
"race" in eth0's collisions and frame values (see below for ifconfig)
that starts a couple minutes after boot. This is driving telnet and
other network connections in the gateway box to a halt.

I think this is not cable (BNC) related as my other 2 machines can ping
each other.

Is there any problem with 2.0 beta 1 that can leads to this kind of
problem? Or am I doing something stupid here?

I first installed 2.0 beta 1 and yesterday did a ftp dselect do get new
packages.

Im using bind, ipmasquerading and squid on the machine.

Can someone help me?
