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/07e3a1cfb0568b6d8d7862077029af96af6690ea
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

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.

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.

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