Comment # 21 on bug 1143331 from Jochen Hansper

I've tried with kernel-firmware-20190618-lp151.2.9.1 from your repository at

http://download.opensuse.org/repositories/home:/tiwai:/branches:/openSUSE:/Leap:/15.1:/Update/standard/noarch/

and it works flawlessly. I've compared /amdgpu from 2.9.1 with the that from
2.6.1 and only vega10_sos.bin has changed (back to 2.3.1), as you said.

Should you need someone to give future amdgpu firmware versions a test run,
I'll gladly do that.

Thanks again for your help and fast support!
