Fix is under discussion here:https://lore.kernel.org/netdev/20200616180352.18602-1-xiyou.wangcong@xxxxxxxxx/Thanks, DanielDear Daniel,thank you for the hint. I will try to follow-up the discussion. For your convenience I have added some of our many and various logs to this thread. Maybe it will be of some help for the team.
There seems to be not much progress in above mentioned thread. Don't know if there have been other discussions that have resulted in a patch.
But last week we successfully tested kernel 5.8.11 (5.8.11-1-MANJARO x64) without experiencing a kernel panic/freeze.. In the userspace systemd 246.6 was running. No idea which changes have solved our issue. But here kernel is back stable again.
We will switch the workstations from intermediate kernel 4.9 LTS, which was stable all the time, back to kernel 5.8.
Thank you.
