Bug#1108250: firmware-intel-graphics: i915 timeout errors after firmware upgrade
Package: firmware-intel-graphics
Version: 20250410-2~bpo12+1
Severity: normal
Dear Maintainer,
After upgrading firmware-intel-graphics from 20240709-2~bpo12+1 to
20250410-2~bpo12+1 I noticed errors in the i915 module that also
caused the display to flicker and shut down. Moreover, X11 sometimes
hung fatally (uninterruptible sleep => only fixable by reboot).
Downgrading firmware-intel-graphics to 20240709-2~bpo12+1 resolved all
issues for me so far.
I am using kernel 6.12.30+bpo-amd64 on an Intel Atom E3826 with
integrated graphics.
Excerpt from dmesg with buggy firmware:

Do you need a full dmesg or more information about my hardware?
Best,
