Description of problem: Using the forcedeth driver for an onboard NIC (nVidia C77 / GeForce 8200) results in bad operating network. Using an alternative NIC (RTL-8169) with the r8169 driver solves the problem. Version-Release number of selected component (if applicable): kernel-2.6.38.8-32.fc15.x86_64 How reproducible: 100% on this specific motherboard. Steps to Reproduce: 1. Upgrade Fedora 14 to Fedora 15 using yum 2. boot 3. Note extreme (but not 100%) packet loss. Actual results: Extreme packet loss Expected results: Operational NIC Additional info: Using tcpdump I see no packetloss when doing a ping. Userspace however hardly ever sees the ICMP replies. Using a still present F14 kernel (kernel-2.6.35.13-92.fc14.x86_64) is a work-around. The forcedeth driver is also used on another PC here, upgrading to F15 however introduced no networking problems. NIC is "nVidia Corporation MCP55". So the issue is highly NIC specific.
Is this still happening in 2.6.43/3.3?
