EXT4 metadata_csum feature (mkfs.ext4 -O metadata_csum ...) requires the crc32c module. One more quirk to add... *sigh*

I just installed Arch according to installation instructions on a new HP EliteBook (i5 Kaby Lake, so might use Intel-specific modules) and it fails to boot for the same reason: ext4 needs crc32c module.

The fallback initramfs boots fine.

I'm somewhat confused as to why this needs manual intervention as I would assume booting with an ext4 root partition is extremely common. Is there some mix-up related to the crc32c-intel variant or did I mess something up?
