I believe this change caudses the following oops on my system:
* Tue Aug 03 2021 jeffm@jeffm.io - config: re-modularize CRYPTO_{CTS,ECB,HMAC,SHA512,XTS} (bsc#1189034). Now that FS_ENCRYPTION_ALGS is modular, the crypto modules it utilizes can be modular as well. CRYPTO_AES and CRYPTO_CBC are used by ENCRYPTED_KEYS and must remain built-in. - commit 5f8b914
I've updated the bug report for this. TL;DR there was a regression introduced in 5.14-rc1. The root cause is that DRBG now tests sha512 on startup and does so before the initramfs is loaded. The commit that made that change didn't add it to the Kconfig option to select it as a built-in. BTW, not an oops, just a warning -- but it would've been a full panic if the system was booted in FIPS mode. I would've CC'd you to the bug but our Bugzilla doesn't do searching for users anymore (yay GDPR) and it's not the same as your email here. Thanks for the report, -Jeff
