Hi , reverting d6b88ce2eb9d ("ACPI: processor idle: Allow playing dead in C3 state") made kernel version 5.15.35 booting , but still not kernel version 5.17.5 in my case.
The last one has changed behaviour : now the kernel seems to boot - at least it is not freezing and key combination works to reboot the machine - but it does not detect ata controller at all and after trying without success to wait for root partition to be detected , it finishes prompting at initramfs emergency console. I'd like to do some more tests to be sure that it is really a kernel boot failure and not an error I've made by messing up something else : anyway config includes ata_generic and ata_pii modules. Just a note about d6b88ce2eb9d : while reading the message of the commit you can see it regards amd cpu _only_ ; it was introduced without inserting neither a conditional check , at least !!
