Package: linux-image-4.9.0-1-amd64
Version: 4.9.6-3
Everything works under kernel 4.8, but have display problems
with x-server, virtual terminals when booting 4.9. Diffs reveal
that the two kernels load different firmware for the graphics card.
Symptoms:
graphics card is wired up to drive three displays.
When xserver/gdm greater starts, third screen never
lights up; monitor states "no input signal".
virtual terminal switching (alt-pf1 through alt-pf6) fails
to change the display. The vt switch did occur: I can
blindly login to a virtual terminal, and run commands
in it; display stays frozen.
Killing/starting X11 fails to do anything at all to display:
no blinking, no refresh; display is frozen.
Graphics hardware:
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Tonga PRO [Radeon R9 285/380] (rev f1)
Diffing the failed and the good boots, I see different firmware
being loaded for these two kernels. Failing boot loads
amdgpu/tonga_k_smc.bin while the working boot loads
amdgpu/tonga_smc.bin
Failing boot looks like this:

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
