Good morning, everyone,
I hadn't updated my coreboot version for a long time on my Asrock
E350M1 card because of lack of time and because this one was on a very

stable version. While trying to test the current 4.12 version, I
encountered problems in Debian 10.
What coreboot version did you use before?
Indeed, there is a bad graphical detection, the resolution of my hdmi
output went from 1360x768 to 720x400 pixels.
Xorg indicates that the drm device cannot be opened :
(EE) open /dev/dri/card0: No such file or directory
I once had a Oops kernel message:

For the future, please attach the logs to the message, so people can
read it offline.
I paste the error below.

Let’s try to find the error in the Linux driver code.
Please install the the debug symbols with
apt install linux-image-<our version>-dbg
and run the script from the Linux tree.
scripts/faddr2line vmlinux sumo_dpm_enable+0x2ed/0x510
I believe, you can also use `scripts/decodecode` feed it the Linux
messages. It will parse the `Code:` line.
[…]
Kind regards,
Paul
