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
