Steps to reproduce:
After upgrading system with pacman -Suy to kernel 5.15.2 it stopped to recognize root partition.
I repeated clean install according to https://wiki.archlinux.org/title/installation_guide and it still doesn't work
If boot from USB live disk (kernel version 5.14.15) everything work fine and disk is recognized

I have the same problem after upgrading to linux 5.15.2.arch1-1 on my MacBook Air 2010. Boot process properly works by downgrading to 5.14.16-arch1-1.

dmesg output log is attached.
`[ 16.403940] ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4)` and following lines seem suspicious.

Same with my MacBookPro7,1.
Downgrading to previous kernel, 5.14.16-arch1-1, also resolved booing issue.
