Bug#1042374: linux-image-6.1.0-0.deb11.9-amd64: The module radeon is unstable, the system reboots often infinitively

[rpnpif <rpnpif@trob.eu>]

After a lot of tests, I have found the culprit of this instability.
If I blacklists the radeon and amdgpu module, all works fine but the 
display resolution is too low.

If I enabled again, as soon as the radeon is loaded, the machine reboots.

If I blacklist radeon and manually I modprobe radeon, the machine 
reboots immediately.

I can start the machine with radeon one times of 5 with the normal mode 
or one times of 2 with the maintenance mode.
After a reboot after a crash, the usb mouse does not work, but on the 
second success, the usb mouse works fine. Restarting the machine after a 
poweroff does never permit a success boot.

firmware-amd-graphics 20230515-3 from SID does not fix this issue.
