Hi, All It seems that I'm getting same problems with 3.5.2 kernel - 80003ES2LAN onboard NIC is going to reset from time to time under load

While reset traffic stop going, iowait increase up to 100% and then link flaps and all became normal until next reset that could happen in 1 hour, or in 1 day. Also I noticed, that resets aren't correlate with traffic load. It could happen ever when NIC is almost idle, transferring ~30-40 mbps. Is there anything we can do to fix this issue?
