Control: forwarded -1 https://lore.kernel.org/amd-gfx/epyf7tdz3azb3fflb6rwuhax7mpccmqlsmzqqe2pcm7mxrdur4@zpx2uo5pvoqs Hello, A Debian user (Roman Savochenko, on Cc:) reports issues (freezing with black screen) with a Radeon HD 8570D graphics adapter. When passing `radeon.dpm=0` on the kernel commandline the problems are gone. Is it a sensible quirk to let dpm default to 0 with that hardware? Or does the behaviour depend on (e.g.) the actual monitor in use? Or is there a bug to fix? If so, do you have a hint what to do, is there more information needed from the affected system? The full bug history is available at https://bugs.debian.org/1118349, which also contains some hardware information. Best regards Uwe

The oldest Linux kernel 6 is only one on the actual Debian 12 installation on this PC: roman@home:~$ cat /proc/version Linux version 6.1.0-33-amd64 (debian-kernel@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT_DYNAMIC Debian 6.1.133-1 (2025-04-10) And the problem is actual here since I have loaded from the kernel only with "radeon.dpm=0": roman@home:~$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-6.1.0-33-amd64 root=UUID=dd0275fe-934a-4742-8f89-0bc5c0357dad ro radeon.dpm=0 quiet splash Regards, Roman

The problem is reproducible on any monitor and video-output due to I tried the same through VGA and TV through HDMI.
