Package: LINUX-IMAGE-5.10.0-16-AMD64
Version: 5.10.127-1

Debian Bullseye, fully up to date.

After an unattended upgrade on 10 July 2022, the system started locking up multiple times per day. This machine is a small office server, including mail, web, database, etc. services and serving files from a zfs pool over NTFSv4 to 5-10 clients on premise.

Some of the kernel panic lines seem to be related to openzfs, others to kvm, which is why I file the bug to this package. Below a list of the kernel panic information extracted from the journals. Since I have downgraded the kernel to 5.10.0.13, the machine is running reliably again.

First kernel panic:

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
