Dear Paulo,

I'll try and get that done. I'm currently in the process of bisecting
the issue on the side.
I'll be back with news hopefully soon.

Thanks!

Best
Sebastian

Yes.  Please provide again the network traces of both working and
non-working kernels along with the session keys in order to decrypt the
packets.

You can retrieve the session keys by running `smbinfo keys
/mounted/share/some/file` [1].

Make sure you can decrypt the packets with dumped keys before sending
those out.

Besides running ls, try to stat those files as well.  If you can
provide
network traces with smbclient(2) [2], it would be great, too.

Thanks.
