    Bluetooth: MGMT: Ignore keys being loaded with invalid type

    Due to 59b047bc98084f8af2c41483e4d68a5adf2fa7f7 there could be keys stored
    with the wrong address type so this attempt to detect it and ignore them
    instead of just failing to load all keys.

Most likely you got an older release without the following fix to userspace:

commit 7322ec38fb65afe8f34b9e363ed9fce37e1ff868

    adapter: Fix up address type for all keys

    66a8c522b64 ("adapter: Fix up address type when loading keys") didn't
    fix all instances of wrong address type being loaded, so peripheral LTK
    and IRK were still left with possible invalid types.

I'm running fully updated Fedora 41 and Linux 6.13.4. Hopefully this will be
fixed in later stable releases.
