Bug#1053120: linux-image-6.1.0-12-amd64: Kernel NULL pointer deref with XFS on kernel 6.1
Package: src:linux
Version: 6.1.52-1
Severity: important
X-Debbugs-Cc: wfhnbsq1@duck.com
Dear Maintainer,
I have been running Debian 12 on a Hetzner cloud VM since a few weeks before the official Debian 12 Stable release. I did a manual netinstall with an XFS root filesystem. Unfortunately
I have consistently been having issues approximately every month with kernel crashes that start like this:
