If this was just the WARNING, I probably wouldn't have even noticed it in the
first place. But the WARNING is just a quick sign that the bug is present,
before things end up on a BUG later on.

As I've reported initially, after the first (mostly harmless) WARNING, things
run fine for a while -- maybe even a few days -- before another WARNING
followed by a BUG happens:

        Oct 07 01:33:15 laptop kernel: ------------[ cut here ]------------
        Oct 07 01:33:15 laptop kernel: kernel BUG at fs/ext4/inode.c:2721!
        Oct 07 01:33:15 laptop kernel: invalid opcode: 0000 [#1] SMP PTI
        ...

This BUG, as the previous commenter notes, causes processes to get stuck in D
mode, as well as new processes becoming impossible to start. The system quickly
becomes unusable, and requires a (hard) reboot.
