Bug#1006149: linux-image-5.16.0-1-686: Fails to boot on T41 Thinkpads

[Francesco C <fc.linuxuser@gmail.com>]

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 !!
