Title:
Netdev watchdog closes link on PowerEdge R6515 Realtek BCM5720
Status in linux package in Ubuntu:
Confirmed
Bug description:
A few months ago we got 3 Dell PowerEdge™ R6515 machines and installed
Ubuntu 20.04 LTS. After a few days problems started showing on the
network interface for the internal network. The network link is
disconnected, and a few seconds later it is connected again. We have
updated all the server firmware, checked the cables and switch but the
problem persists. Digging deeper in the logs we found this in dmesg
(full log in the attached file):
[Sat Jan 30 09:57:07 2021] NETDEV WATCHDOG: eno2 (tg3): transmit queue 0
timed out
[Sat Jan 30 09:57:07 2021] tg3 0000:c1:00.1 eno2: transmit timed out,
resetting
[Sat Jan 30 09:57:08 2021] tg3 0000:c1:00.1 eno2: Link is down
[Sat Jan 30 09:57:12 2021] tg3 0000:c1:00.1 eno2: Link is up at 1000 Mbps,
full duplex
For some reason, the link is disconnected and reconnected a few
seconds later. This happens randomly on all 3 servers and it does not
seem to correlate with the current traffic on that interface. The
problem seems to be very similar to Bug #1331513 but this happens on
the up to date Ubutnu 20.04 (last updated mid last week).
If you need any additional info, feel free to ask.
