Hi,
I’ve been running LEAP 42.3 for months with an AMD A8-9600 R7 IGP (Carizzo) using amdgpu with no problems: full desktop effects, HW decoding of .h265 etc. I had been using a Kernel from the Kernel:HEAD repository from the start, because that gave me proper suspend-to-ram, which did not work with the standard Kernel. But the graphics had been working with the standard Kernel, too.
Then, about a week ago, after a regular software update which included a kernel update, my graphics were broken:
- When booting, most of the time, after I see the first few lines of boot screen logging, the display briefly flashes and then turns off, with the monitor going to standby. Then the monitor comes back on, but stays black. Also, switching to other terminals (Ctrl-Alt-F1) does nothing.
- About one out of 10 times, the system comes up to KDE properly, but no accelerated graphics like desktop effects, HW video decoding etc.
- I can reliably boot in recovery and then startx, but that obviously does not have accelerated graphics, either.
- Behavior is the same no matter which version kernel I boot - in particular also the kernel that had been working fine before has the above issues now.
So in order to clean things up, I removed all newer Kernels and installed the latest from opensuse-updates, 4.4.104-39-default. But this did not help either, still the same behavior.
I have the latest opensuse-update versions of “kernel-firmware” and “xf86-video-amdgpu” installed, so should be matching the kernel.
I also have a bunch of packages (mostly “lib*”) with “vdpau” or “amdgpu” in the name, and “ucode-amd”. I have made sure those are all the most recent from opensuse-update, too. I did not change anything there in a long time, so that might not be the issue.
One peculiar thing is that when I run mkinitrd, I get a bunch of lines like
dracut: Possible missing firmware "amdgpu/stoney_ce.bin" for kernel module "amdgpu.ko"
dracut: Possible missing firmware "amdgpu/carrizo_rlc.bin" for kernel module "amdgpu.ko"
dracut: Possible missing firmware "amdgpu/carrizo_mec2.bin" for kernel module "amdgpu.ko"
dracut: Possible missing firmware "amdgpu/carrizo_mec.bin" for kernel module "amdgpu.ko"

dracut: Possible missing firmware "amdgpu/carrizo_ce.bin" for kernel module "amdgpu.ko"
dracut: Possible missing firmware "amdgpu/topaz_sdma1.bin" for kernel module "amdgpu.ko"
But these files are clearly present:

More info:

So no “vga=” or anything.

So it seems the amdgpu driver is loaded and used.

So no HW decoding.
Any help or ideas would be much appreciated…
Thanks a lot in advance!
