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. [AMD/ATI] physical id: 0 bus info: pci@0000:0c:00.0 version: c1 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=amdgpu latency=0
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

--- Comment #3 from Matej Lach me@matej-lach.me --- I can confirm this bug is indeed present. Worth noting that the screen is only blank on the laptop built-in display, (after KMS), external monitors work fine.
Adding `amdgpu.dc=0` to the kernel parameters resolves the issue for me, but this was not necessary before kernel 4.19.9, so it seems like a regression. [1] seems related.

--- Comment #4 from Nicholas Kazlauskas nicholas.kazlauskas@amd.com --- This should be fixed by: https://patchwork.freedesktop.org/patch/264792/
It's probably why you don't see the issue occur in 4.20-rc7.

Looks like the stable patch autoselect strikes again! Does this backported patch fix the issue?
