Hello, I apologize I'm not a developer, but want to try helping in fixing a bug with the forcedeth driver. I use SUSE 10.0 with all updates and actual kernel 2.6.13-15.8 as provided from SUSE (just self compiled to optimize for Athlon64, SMP, and HZ=100), with an Asus A8N-E motherboard, and an Athlon64x2 CPU. The onboard network card is this: 00:0a.0 Class 0680: 10de:0057 (rev a3) 00:0a.0 Bridge: nVidia Corporation CK804 Ethernet Controller (rev a3) Subsystem: ASUSTeK Computer Inc. K8N4-E Mainboard Flags: 66MHz, fast devsel, IRQ 50 Memory at 00000000d3000000 (32-bit, non-prefetchable) [size=4K] I/O ports at b000 [size=8] Capabilities: [44] Power Management version 2 and the problem is that it hangs and stops working when there is a higher load. Even before that, there seems to be a disturbance, as I/O was quite slow: Linux server, Apple client: FTP/NFS, etc all slow. I put a Realtek8169 into the system and now it works perfect, so its obviously a driver bug, as I have the same hardware in another place showing the same behaviour (works on very low load, stops when really used). Is there a workaround?
