Description

Further testing shows that the problem happens on the SMP kernels only. The single-processor kernels apparently are not affected by it. Francois Romieu provided a patch that when applied to kernel-source-2.6.5-1.319 solves the problem. The link to this patch is: http://www.fr.zoreil.com/people/francois/misc/20040407-2.6.5-r8169.c-stable.patch I too have a Realtek RTL-8169 and it bugs out every 2-4 days (Fedora Core 2, kernel 2.6.8-1.521). When it happens, I once saw the console flooded with the message: eth0: Too much work on interrupt The kernel appears to be locked up completely when this happens. Network traffic has not been very high. Should I open a new ticket for this? I had this problem too on a Pentium 4 HT machine, running SMP kernels. I solved it by adding the noapic option to the kernel at boot time. Since I did this the problem stopped. I never experienced this bug when running UP kernels. Please use the patch referred below to sync your kernel with a recent vanilla kernel. Amongst many things, napi could make a difference. If the symptoms do not disappear, consider opening a new ticket and Ccing me. Btw, assuming people are not hit by r8169 unrelated issues, the driver has already shown to be quite stable on real SMP systems. Patch available at: http://www.fr.zoreil.com/linux/kernel/2.6.x/2.6.8-1.521/r8169.c-2.6.8-1.521-to-2.6.9-rc2-dac.patch |
