I want to add one thing: there is a log entry in the dmesg output of a "bad" kernel, which 
I initially overlooked, because it is way up, and I noticed this just now. I guess this 
might be relevant:

[    1.683564] [Firmware Bug]: CPU0: Topology domain 0 shift 1 != 5

This does not appear in the 6.8 kernel dmesg.

What do you think?

Beste Grüße,
Peter Schneider
