Since upgrade to 9.6 logs are full with
kernel: e1000e 0000:00:19.0 eno1: Detected Hardware Unit Hang:#012 TDH
looks like disabling all offloads helps.
I have this too on multiple machine and is causing them to lose network connectivity.
I can’t see a bug report for this, did you file one.
I also can’t see anything with the upstream
No, I did not create bug report.
Workaround is:
[Unit]
Description=ethtool configuration to enable workaround for specified card
After=network-online.target
Wants=network-online.target
[Service]
ExecStart=/usr/sbin/ethtool -K eno1 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off
Type=oneshot
[Install]
WantedBy=multi-user.target
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) (rev 05)
Looks like only this chip is affected in my case, because other servers have no problems.
