I have the following videocard 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 665f (rev 81) (prog-if 00 [VGA controller]) Subsystem: XFX Pine Group Inc. Device 7360 I use radeon driver. That works for kernels 4.1 through 4.7. Starting with kernel 4.8 through 4.10 it fails to load the firmware and keeps the monotor black. I can log in to the system using ssh, but X11 does not start. Here are the messages: [drm] initializing kernel modesetting (BONAIRE 0x1002:0x665F 0x1682:0x7360 0x81). radeon 0000:03:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff ATOM BIOS: C93602 radeon 0000:03:00.0: VRAM: 2048M 0x0000000000000000 - 0x000000007FFFFFFF (2048M used) radeon 0000:03:00.0: GTT: 2048M 0x0000000080000000 - 0x00000000FFFFFFFF [drm] Detected VRAM RAM=2048M, BAR=256M [drm] RAM width 128bits DDR [drm] radeon: 2048M of VRAM memory ready [drm] radeon: 2048M of GTT memory ready.

You probably need to update the initrd, so that /usr/lib/firmware/radeon/bonaire_k_smc.bin is included in it. Resolving as not a bug, the microcode is required.
Correct. What I needed: 1) update kernel; 2) update firmware; 3) update initrd; 4) reboot. Just in that sequence. This fixed the problem. Thank you for the helpful hint.
