Reverting that results in a working SMP kernel, at least up to version 5.8.y.
Great! I hoped you would have a look. :-)
There is another problem (causing occassional memory corruptions in user space) introduced into the 5.9.0 kernel which has proved tricky to nail down. I have an idea where it is but not what the actual problem is.
I think I can confirm that, because the panic on my DS25 with 5.15.0-1 looks different than with 5.4.0-1. I didn't create a log, but IIRC the panic originated from systemd there. How should we proceed from here? Cheers, Frank
