After upgrading to linux-libre 4.20, and again tested with 4.20.3, an
aarch64 system failed to boot (using 4.19.10 worked fine):

Workaround or fix was to add to config.scm:
(initrd (append (list "crc32c_generic" ... ) %base-initrd-modules))
4.19.10 and earlier worked fine without this addition; as far as I can
see the relevent kernel configurations are all present; but some
behavior changed with the ext4 driver; Is the initrd no longer including
soft module dependencies? (e.g. for optional ext4 features)
This seems similar to Debian bug:

There are potentially two issues here:
1. Why wasn’t crc32c_generic.ko automatically pulled in by the initrd
build code? Isn’t it a dependency of ext4.ko?
2. Is crc32c_generic built-in in our x86_64 kernel config?
Thanks,
Ludo’.

It is not a hard dependency, no. It's an optional feature only needed if
certain ext4 features are enabled on the filesystem (maybe metadata_csum
in this case?). So it's listed as a MODULE_SOFTDEP of ext4:
fs/ext4/super.c:MODULE_SOFTDEP("pre: crc32c");
> 2. Is crc32c_generic built-in in our x86_64 kernel config?
On x86_64:
$ grep CRC32 /gnu/store/*linux-libre*4.20.4*/.config
CONFIG_CRYPTO_CRC32C=y
CONFIG_CRYPTO_CRC32C_INTEL=y
CONFIG_CRYPTO_CRC32=m
CONFIG_CRYPTO_CRC32_PCLMUL=m
CONFIG_CRC32=y
# CONFIG_CRC32_SELFTEST is not set
CONFIG_CRC32_SLICEBY8=y
# CONFIG_CRC32_SLICEBY4 is not set
# CONFIG_CRC32_SARWATE is not set
# CONFIG_CRC32_BIT is not set
CONFIG_LIBCRC32C=m
On aarch64:
$ grep CRC32 /gnu/store/*linux-libre*4.20.3*/.config
CONFIG_CRYPTO_CRC32C=m
CONFIG_CRYPTO_CRC32=m
CONFIG_CRC32=y
# CONFIG_CRC32_SELFTEST is not set
CONFIG_CRC32_SLICEBY8=y
# CONFIG_CRC32_SLICEBY4 is not set
# CONFIG_CRC32_SARWATE is not set
# CONFIG_CRC32_BIT is not set
CONFIG_LIBCRC32C=m
on aarch64 4.19.10 also contained:
CONFIG_CRYPTO_CRC32_ARM64_CE=y
Which is no longer available in 4.20.x upstream in commit
598b7d41e544322c8c4f3737ee8ddf905a44175e.
So my hunch is that crc32c-ce was used in 4.19.x, but 4.20.x needed the
generic crc32c implementation.
live well,
vagrant

Interesting. Should we add support for soft dependencies in (gnu build
linux-modules), and pull in soft dependencies in the initrd? Currently
we only do that for hard dependencies.
That wouldn’t help in this case since ext4 is built-in. So my guess is
that for this particular case we should probably just change the AArch64
kernel config so it matches the x86 ones.
Thoughts?
Thanks,
Ludo’.
