This makes any box with this NIC unusable. I observed this issue already with openSUSE 12.1 Tumbleweed and kernel 3.4 and could only solve the problem by stepping back to kernel 3.1. This is a quite frequently observed problem with these on-board Realtek chipsets. A patch was recently posted here: https://bugzilla.kernel.org/attachment.cgi?id=73504 (see https://bugzilla.kernel.org/show_bug.cgi?id=14962#c27 for details). The patch has made it into kernel 3.5 but not into 3.4.6 or 3.4.7. To my knowledge openSUSE delivers kernels with extra patches. I therefore suggest to integrate that simple patch into the openSuSE kernel 3.4. Reproducible: Always Steps to Reproduce: Use a box with a mainboard with Realtek 8111B chipset, install 3.4er kernel, initiate some network activity while pinging another host. The pings will stop every now and then and, when the NIC comes back to live, the roundtrip time shown is about 10 to 20 seconds(!). I will ask Francois Romieu to backport his patch to 3.4.6 and 3.4.7 kernel series. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
