Hi Bernard,

    This is the same issue that I and a few other folks have run into.
Please see the analysis in
https://lore.kernel.org/linux-hams/CAEoi9W4FGoEv+2FUKs7zc=XoLuwhhLY8f8t_xQ6MgTJyzQPxXA@mail.gmail.com/#R

    There, I traced the issue far enough to see that it comes from
`sbk->dev` being NULL on these connections. I haven't had time to look
further into why that is, or what changed that made that the case. I
now think that this occurs on the _first_ of the two loops I
mentioned, not the second, however.

        - Dan C.

(Aside: I'm pretty sure that `linux-hams@...r.kernel.org` is not a
Debian-specific list.)
