Description Leonid 2017-02-23 04:53:42 UTC 
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:

I removed contents of /usr/lib/firmware/radeon/ and copied there 246 files found in
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/radeon

I do have /usr/lib/firmware/radeon/bonaire_k_smc.bin that is 130796 bytes long:

53fcd7884233b08265e25a9774c551a8  /usr/lib/firmware/radeon/bonaire_k_smc.bin

Any ideas how to fix it?
Comment 1 Michel Dänzer 2017-02-23 06:16:09 UTC 
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.
Comment 2 Leonid 2017-02-23 17:02:55 UTC 
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.
