--- Comment #4 from Thomas DEBESSE <dev at illwieckz.net> ---
> The attached patch should fix it. pwm control is only available with dpm,
and you've disabled dpm via the kernel command line.

Oh yes, the last grub update (fortuitously made the morning before I change
my GPU for the one described above) introduced a "radeon.dpm=0" default
kernel command line option, probably to workaround that other bug
https://bugzilla.kernel.org/show_bug.cgi?id=103271

Thank you for your fast answer, I will try both (the patch and the kernel
command line option).

On which source tree this patch must be applied?
