I also went looking for traces of the missing module:
> find /usr/lib/modules/$(uname -r) -name '*crc32c*'
/usr/lib/modules/6.17.1-arch1-1/build/include/linux/crc32c.h
> sudo mkinticpio -Pv # output does not show any error other than "==> ERROR: module not found: 'crc32c_generic' "
> sudo lsinitcpio /boot/initramfs-linux.img | grep crc32
usr/lib/modules/6.17.1-arch1-1/kernel/crypto/crc32-cryptoapi.ko.zst
usr/bin/crc32I thought the crc32c_generic module was part of the mainline kernel and I did not see any announcement about it on the Arch home page.
I am obviously missing something........ x-(
**EDIT**:
> sudo tune2fs -l /dev/nvme0n1p8 | grep features
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent 64bit flex_bg sparse_super large_file huge_file dir_nlink extra_isize metadata_csum
+[11/619]3.13.7 ~ \> zcat /proc/config.gz | grep CONFIG_CRYPTO_CRC32C
CONFIG_CRYPTO_CRC32C=yso that host's system is not crazy, it does need crc32c to do its metadata checksum. But if crc32c is ineed included in the kernel (therefore not needed as a kernel module) why on earth does it complain loudly about some missing crc32c ?
Am I doing something wrong here or is it on kernel 6.17.1-arch1-1 ?

Re: [SOLVED] ERROR: module not found: 'crc32c_generic' (6.17-arch1-1)
Works fine here (doesn't pop up a warning), check/post your mkinitcpio.conf do you explicitly include it there for some reason?

Re: [SOLVED] ERROR: module not found: 'crc32c_generic' (6.17-arch1-1)
modinfo crc32c_genericIt's built-in, just remove it from the MODULES array in your mkinitcpio.conf?

Re: [SOLVED] ERROR: module not found: 'crc32c_generic' (6.17-arch1-1)
Yes, It was on ME not on kernel 6.17-arch1-1 (would have been surprising).
I cleaned up mkinitcpio.conf ('crc32c_generic' was included in a long MODULE= line and somehow I did not see it staring me in the face last night.)
Rebuilt initramfs. All is well.
