If my machine goes over 100mbit it stops responding

I recently converted a FreeBSD 7 machine to Arch Linux (2.6.35) and now whenever it goes over 100mbit it stops responding. I thought it might have just been network problems so I got KVM over IP from my datacenter and the console is frozen as well when it happens. No helpful errors in /var/log/* or on console either.

/var/log/dmesg.log wrote:

Re: If my machine goes over 100mbit it stops responding

Wow, very interesting.  I have a buddy that had complaints about similar networking problems too.  I believe that when his networking situation became a problem, the CPU usage on the machine started to get high.  Does this occur on yours too?

Re: If my machine goes over 100mbit it stops responding

The CPU and HDD loads would defiantly be getting high by the time the machine was going over 100mbit. I actually have just assumed its the network triggering the lockup, could be the CPU HDD or network I suppose as they all rise together. Throttling it to 100mbit keeps it from locking up though.

Back to FreeBSD then I guess.

Check if your network chipset isn't overheating (use your finger to see that... its easy to feel when there are problems tongue ) My r8169 get's extremely hot and I now have an heatsink on it to help cooling (and the heatsink gets super hot to touch, imagine without it...).
never had any network failure.

What would I need KVM over IP for if I could touch the chipset tongue
