Public bug reported: Hardware: Intel D945GCLF with onboard Realtek R8101 LAN controller. OS: Ubuntu 16.04.1 LTS Server Edition - upgraded from 12.04 LTS
By default Ubuntu chooses the r8169 module for this controller, which does not work correctly. (This has been an issue for a number of releases). Realtek provide a Linux driver at the below site: http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=7&Level=5&Conn=4&DownTypeID=3&GetDown=false With previous Ubuntu releases, compiling and using this module has worked perfectly, however with Ubuntu 16.04.1 I have had limited success. I have downloaded and compiled v1.030 and used it with a number of supported kernels but am getting similar issues with all. Note that I have also disabled IPv6 on this machine having seen indications that this may be causing the problem - I have seen no change in behaviour since doing this. Kernel 4.4.0-34-generic > Immediately following boot (or depmod r8101) the interface works and I can > successfully communicate over the interface I have seen consistent downloads > of 6MB/s. At a seemingly random point later, connectivity will cease without > warning. At this time the stats (RX/TX bytes/packets) in ifconfig cease to > increase but the interface remains UP. A ping to the locally configured > static IP returns successfully. "ifdown && ifup" does not fix the problem, > but "rmmod && depmod" does. The point at which the connectivity ceases does > not appear to be consistent in either time or amount of data transferred. Will append further debugging information when I can get it off the server. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: ethernet networking r8101 ** Tags added: r8101 ** Tags added: ethernet networking -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654559 Title: r8101 unstable under 16.04.1 various kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1654559/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
