=====================================================================

I saw an upstream bug report (https://bugzilla.kernel.org/show_bug.cgi?id=208883), however the backtrace is different so I'm not 100% sure if it's the same issue or not.

Regards,
Daniel

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
