Bug ID: 209721 Summary: No output after AMDGPU loads. Product: Drivers Version: 2.5 Kernel Version: Linux Master branch Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: haxk612@gmail.com Regression: No
I sadly cant even get an dmesg from journalctl or anything. when i enable loglevel8 it shows me that fb0 is giving word to AMDGPU module and then screen goes black turns back on but no output at all.
System Specs: Acer Nitro 5 AN515-42 GPUs: AMD Vega 8 (iGPU in Ryzen 5 2500U) AMD Radeon RX560X (dGPU)
If there is any way you know of to be able to grab logs i will gladly do it.
It should be noted that 5.9 tag works just fine. So the bug was introduced in one of the drm-next merges.
