The other person with the i7-1255U in the meantime got back to me with the needed outputs:
- output of cpuid -r

So this is inconsistent already. Both leafs should describe the same topology. See the differing EAX values (6/7) in subleaf 1, which are exactly the values the kernel complains about :)
But that should not be an issue because the kernel preferres 0x1f over 0xb and will never evaluate both, but this is just from one randomly picked CPU.
I wonder which variant of the cpuid tool that is. cpuid -r gives you usually just the plain values and collects them for all CPUs.
The previously attached one is output from the version located here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tool...
The one I have now attached is the one being built from this: https://www.etallen.com/cpuid.html
