Title:
r8101 unstable under 16.04.1 various kernels
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
