--- Comment #4 from Vladimir G. Ivanovic (vladimir@acm.org) ---
I am getting the same error as sander44 (the OP) reported except the name of
the program generating the error is different.

EXT4-fs error (device sdb1): __ext4_find_entry:1612: inode #2: comm vorta:
reading directory lblock 0

The behavior of the Samsung 1TB SDXC card is predictable. It works for
minutes/hour, then throws the above error. This particular SD card is used =
for
borg backup which occur every 15 minutes (and also every 3 hours).

My (temporary) workaround is to unmount the SD card, run e2fsck, then re-mo=
unt
the card.

I'm suspicious of this being exclusively a hardware error because it is alw=
ays
the same error at the same spot. Might it be an unexpected call or unexpect=
ed
function arguments? (I have no knowledge of ext4 internals, so it's likely =
I'm
talking nonsense.)

I'm happy to provide more detail or even roll my own kernel to provide
debugging symbols. (I'm using Arch 5.15.43-1-lts, but the error is independ=
ent
of what kernel I'm using.)
