Keep an eye on "nomodeset=1".  I noticed it was still activated in the
logs you sent (maybe those were logs from the wrong boot?  Maybe
/etc/default/grub was edited, but grub-update wasn't run, so these
changes weren't applied)

The line "[drm:amdgpu_init [amdgpu]] *ERROR* VGACON disables amdgpu
kernel modesetting" is a consequence of booting with "nomodeset=1" as a
kernel argument.  Sorry I didn't highlight that important detail to the
first step.  That might be a red herring though.  See my question to
Vincent below for more info.

It is likely you'll need to completely remove amdgpu-pro if you want to
use the Debian-provided drivers, because amdgpu-pro installs its own
firmware to a location that overrides firmware-amd-graphics'.  IIRC
amdgpu-pro installs to /lib/firmware/kernel-version/amdgpu, where
firmware-amd-graphics installs to /lib/firmware/amdgpu.

I hope it's not too frustrating that the BTS is English-only!
Francophone forums are available here, by the way:
  https://www.debian.org/international/French

I'm usually in #debian-quebec (un canal bilingue) on irc.oftc.net, and I
expect #debian-fr would be comparably friendly :-)

Thanks Vincent, yes, I just confirmed that CONFIG_DRM_AMD_DC_DCN3_0 is
missing from last week's linux-signed-amd64 (5.10.5+1)!  Presumably an
attempt to load the firmware isn't made unless PCI IDs match, and
without CONFIG_DRM_AMD_DC_DCN3_0 the amdgpu driver doesn't know about
the new PCI IDs?  If so, could you reassign this bug to the kernel
package?

Best,
Nicholas
