--- Comment #3 from Eric Biggers (ebiggers3@...il.com) ---
It sounds like the problem is that one of the inodes on your filesystem was
previously corrupted in such a way that it had unknown flags set.

Then one of these flags was assigned a meaning, causing things to break.

Running e2fsck v1.45.4 or later on the filesystem should fix this by clearing
the casefold flag.  Can you try that?

I'm not sure there's anything else to do here, unless we were to make the
kernel ignore unexpected flags.  Ted, have you considered that?  And it is
intentional that e2fsck ignores unknown flags?
