I have not been able to reproduce this issue so far. I don't have the exact same HW, but I tested on stock 2.6.31 with 82541 based NIC. More than 3 days now of stress without a problem.

If the reporter can provide some additional information that may be of help:
1. cat /proc/interrupts
2. ethtool -i ethX (where ethX is the interface that is causing the problem
3. lspci -vvv
4. ethtool -e ethX
5. specific settings that may deviate from the default configuration (like MTU)
6. type of traffic that is causing the issue.

Thanks,
Emil--
