I am using F2FS as my root filesystem. Today I upgraded from 5.9.11-gentoo to 5.10.1-gentoo. After I upgraded glibc programs could not find libstdc++.so.6. Long story short at least /etc/env.d/00glibc and /etc/nsswitch.conf became corrupt, and when on kernel 5.10.1-gentoo I could consistently cause the problems below (twice including a reboot, filesystem checked with a LiveCD). When switching back to 5.9.11-gentoo, upgrading glibc did not cause any further issues.

"The software crashes, hangs, or causes you to lose data." fits the > description closely. Yes, but it's a testing version, it only happens on F2FS and 5.10 has been buggy since it came out ;) Nevertheless it's fixed, however given the circumstances I would stick to a more stable release since 5.10 stepped out pretty bad.
I'd like to add that I've triggered the bug twice as well and can confirm that this patch resolves the issue.
