(In reply to Alex Deucher from comment #20) > Is it the firmware that caused the regression? Does everything work with > the old firmware? i did the following experiments: 1. via kernel parameters in grub.cfg i changed amdgpu.dc from -1 to 1 amdgpu.msi from -1 to 0 amdgpu.audio from -1 to 0. i installed version 20180119.2a713be-2 of linux-firmware. result: during the second suspend the screen went black (no signal) and the following thaw produced the slow box syndrome... 2. via kernel parameters in grub.cfg i changed amdgpu.dc from -1 to 1 and left amdgpu.msi and amdgpu.audio untouched. i installed version 20180119.2a713be-2 of linux-firmware. and version 20180104.65b1c68-1 of /usr/lib/firmware/amdgpu/polaris12_uvd.bin (package linux-firmware). now it works three times in a row... the 3rd time there even was a running mplayer, that uses HDMI Audio... :) what is that new polaris12_uvd.bin good for? -arne
