Re: Kernel 6.9 regression: X86: Bogus messages from topology detection

Hey Peter,

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.

I also can't comment on whether this is relevant or not, but I have noticed this in more places:
