Bug ID: 109122 Summary: blank screen on rx580 starting with kernel 4.19.9 Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: critical Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: velemas@gmail.com
After upgrading to kernel 4.19.9 in Arch Linux I have a blank screen. The system is unusable.
My system is Asus ROG GL702ZC with RX 580:
lspci output: description: VGA compatible controller product: Ellesmere [Radeon RX 470/480/570/570X/580/580X] vendor: Advanced Micro Devices, Inc.

dmesg: [drm] initializing kernel modesetting (POLARIS10 0x1002:0x67DF 0x1043:0x1A60 0xC1).
The culprit is https://github.com/torvalds/linux/commit/07e3a1cfb0568b6d8d7862077029af96af6...
Reverting it fixed the issue. I also tried 4.20-rc7. There is no issue there. But 4.19.11 still has it.
Setting amdgpu.dc=0 also helps with 4.19.9 - 4.19.11
