Bug#1124463: linux-image-6.17.13+deb14-amd64: One time kernel NULL pointer dereference, trace shows lp and parport
Package: src:linux
Version: 6.17.13-1
Severity: important
X-Debbugs-Cc: tranphuocthanh01@gmail.com
Dear Maintainer,
* What led up to the situation?
I noticed that my system is taking longer than usual to boot, so I
investigated and found that the systemd-modules service hanging for
quite long (>2 mins).
* What exactly did you do (or not do) that was effective (or
ineffective)?
I hard-resetted the laptop and changed to an older kernel. After some
searching around, I tried to recreate the problem unsuccessfully.
Subsequent boots of this suspected kernel did not exhibit the error.
I noticed Bug #1124075 regarding lp crashes in 6.17.12, which is the
closest to what I'm having. I tried the reporter approach of manually
unloading and loading lp/parport using 'sudo modprobe -v lp' and 'sudo
modprobe -v parport'. Found no error with 'dmesg -w'. parport can not be
unloaded due to being in use.
Here's the excerpt from the journalctl command for the boot with error:
