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:
