I'm running Debian Testing on a Kino-945GSE motherboard which has 2 Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controllers. Only one of these is in use.
Kernels newer than Linux tuscan3 4.3.0-1-686-pae #1 SMP Debian 4.3.5-1 (2016-02-06) i686 GNU/Linux suffer from Bug#812746 which writes errors of "r8169 0000:02:00.0 eth0: rtl_counters_cond == 1 (loop: 1000, delay: 10)." every 30 seconds or so and makes console operation almost impossible. The only workaround I have so far found is to avoid kernels later than 4.3.0-1 including the recent linux-image-4.11.0-1-686-pae 4.11.6-1. I attempted to use the r8168-dkms package but have been unable to build this with 4.11.0-1 as it errors with "error: ‘struct net_device’ has no member named ‘last_rx’" Googleing finds that there is a patch to r8169.c for example: https://patchwork.ozlabs.org/patch/541393/ but his doesn't seem to have made it into the current Debian kernels. If anyone can suggest a workaround that will allow the use of recent kernels I would very much appreciate their help. TIA Rob
