--- Comment #6 from Vadim Girlin ptpzz@yandex.ru --- Created attachment 134152 --> https://bugs.freedesktop.org/attachment.cgi?id=134152&action=edit dmesg after failed resume
The latest amd-staging-drm-next branch fails to resume from suspend properly for me. It worked previously (when it was possible to perform a suspend).
After resume the screen is mostly blue now with some dynamic random noise - horizontal black lines etc. Though I hear the sound via the display port audio from the video that was playing at the moment of suspend, so at least that part seems to work.
There are some amdgpu backtraces in the attached dmesg before and after the suspend/resume, but I didn't notice any real issues before suspend so far, the only problem is that the display is unusable after resume.
