Title:
Network randomly went offline and had to be manually restarted (r8169)
Status in linux package in Ubuntu:
Confirmed
Bug description:
Description of the problem
While in the middle of a copy the network interface (which uses the r8169
driver) went offline. Downing and then upping the interface restored
connectivity.
Steps to reproduce:
1. Check out a large subversion repository over HTTPS?
Expected results:
Network card to be online throughout the whole checkout.
Actual result:
Network card went offline and the following messages appeared in the logs:
[89578.447799] r8169 0000:02:00.0 enp2s0: NETDEV WATCHDOG: CPU: 5: transmit
queue 0 timed out 5640 ms
[89578.447920] r8169 0000:02:00.0: can't disable ASPM; OS doesn't have ASPM
control
[89630.254720] r8169 0000:02:00.0 enp2s0: NETDEV WATCHDOG: CPU: 7: transmit
queue 0 timed out 5001 ms
[89630.254839] r8169 0000:02:00.0: can't disable ASPM; OS doesn't have ASPM
control
Additional information:
On tty1 running the networkctl reported the following:
# networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 enp2s0 ether degraded configured
2 links listed.
networkctl down enp2s0; networkctl down enp2s0
caused networkctl to then report
# networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 enp2s0 ether routable configuring
2 links listed.
Before it finally went to the following:
# networkctl
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 enp2s0 ether routable configured
2 links listed.
After doing some cleanup and the checkout was resumed and ran to
completion.
How reproducible is the problem?
I've installed the system a day ago and this is the first and only time this
has happened. It managed to do a big transfer over SSH to a local machine that
took over 12 hours to complete without issue...
