Hello everyone,
I could use some help to figure out why my PVE instance crashes randomly. I am running version 6.14.8-2-pve on a Lenovo ThinkStation P360 which I repurposed from a regular desktop machine to run PVE.

Pulling the logs, I can see the following when PVE becomes unavailable and I have to do a hard reboot:

Code:
May 15 00:00:00 pm kernel: e1000e 0000:00:1f.6 eno1: Detected Hardware Unit Hang:
                             TDH                  <b9>

                             next_to_use          <d3>
                             next_to_clean        <b8>
                           buffer_info[next_to_clean]:

                           PCI Status             <10>

Any suggestions what I can do to prevent PVE from crashing on me? I am using barely any hardware so it shouldn't be a heat related problem (I assume).
 
Thanks daanw, much appreciated! I ran the following command and will keep monitoring PVE for any potential hardware unit hangs.

Code:
ethtool -K eno1 gso off gro off tso off
