Both kernels also fail to reboot the machine. Runit says:

- runit: system reboot

And then nothing anymore.

It is not just hibernation.

I think ThinkPad T14 AMD Gen 1 or similar systems with Linux are not that 
rare. I am surprised this is not hitting more people. Well maybe it does 
and no one reported it here.

Well let's see what happens when 6.7.12 hits distribution kernels.

Anyway, I have an actionable git bisect between 6.7.11 and 6.7.12, just 
not today. Maybe beginning of next week.
