After the upgrade from linux-5.8.14 to linux-5.9.1 I experienced complete loss of 3 ethernet interfaces. Only the dedicated IPMI one seems to have survived. Downgrading back to 5.8.14 fixes the issue. I already filed an upstream bug report about it.

Additional info:
* linux-5.9.1

It's exactly the scenario I experience.

No, haven't tried 5.10-rc1. I don't get to test such a fresh kernel :) (generally sticking with the latest stable).

The fix being queued for 5.9 is also very good news.

Thank you very much anyway for pointing me to these commits. Couldn't find anything relevant by searching in bugzilla or google.
