That is a reopening the bug #879992, which reproduction started from Debian 9
on AMD A8-6500 APU.

And only Debian 11 is where the bug was not reproducing on Linux kernel 5.

>From Debian 12 (any Linux kernel 6) and now in Debian 13 it is obligatory
reproducing not as restarting but freezing with black screen and on any kernel
6 version (also 6.16.3+deb13-amd64).

And it is worarounded only by the kernel option "radeon.dpm=0".

Can you please provide the output of `lspci -nn`. With that input a
quirk can be added that make the parameter dpm default to 0 for your
hardware.


Sure please:
