Intel I219-LM Random Disconnects

[KremitFrog]

We are a MSP and have seen 5-6 Dell machines out of hundreds in our deployment recently start randomly disconnecting the ethernet adapter for a few seconds to about a minute, then the adapter restarts and works again. This can happen a few times a day, or dozens.

When this happens, we see Event ID 27 e1dexpress

and Event ID 10400 NDIS:

The network interface "Intel(R) Ethernet Connection (7) I219-LM" has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets. Reason: The network driver detected that its hardware has stopped responding to commands. This network interface has reset 1 time(s) since it was last initialized.

We have tried several different ethernet drivers, including Intel's latest, as well as older drivers from 2019, we have disabled power saving features and advanced power saving stuff in the advanced tab from device manager. We had a Dell technician come out and replace the entire motherboard on one machine, and the issue persisted immediately after booting it back up.

Any idea what is going on or how to fix? Every one of the machines with this issue is running Windows 10 x64 (21H1 / 21H2 Preview) with the latest updates installed.
