I'm attaching the stacktrace [1] and decodecode [2] at the end, generated
on 6.1.92 vanilla+patch (1.).

Looks like it was a miss :(
I tested the recent release version 6.1.92, and the bug is still
reproducible.
Interestingly, I encountered fewer occurrences with this release..
I then applied the patch mentioned (1.), but the bug is still
(immediately) reproducible.
The stack traces are the same for version 6.1.92, both with and without
the patch.
I understand that 6.9-rc5[1] worked fine, but I guess it will take some
time to be
included in Debian stable, so having a patch for 6.1.x will be much
appreciated.
I do not have the time to follow the vanilla (latest) release as is
likely the case for
many other Linux users.
Let me know if there's anything else useful I can do for you.
Thank you,
Mike
