AMD RX 570 Black Screen at boot

[Surena Karimpour]

Ubuntu 19.04

Problem:
Booting from live media OR installed ubuntu fails with a blank, black screen and total system hang.

How to reproduce:
Using AMDGpu driver and AMD 4th Gen GCN GPU, try to boot Ubuntu 19.04 (or 18.04)

Resolution:
Manually updating kernel to 5.1 and adding the "amdgpu.dc=0" kernel boot parameter seems to fix the problem.

Please also test with the default 19.04 kernel (ideally the installer, too), can you get graphical output there using amdgpu.dc=0 ?

While running from the installed system, if possible using the default (after updates) kernel image, with amdgpu.dc=0 set, please run:
  apport collect-logs 1837945

[Surena Karimpour (sudohalt)]

I re-installed ubuntu 19.04 and the amdgpu.dc=0 fixed it in the installer, also I tested with the default kernel (latest update) and can confirm amdgpu.dc=0 works on default kernel as well, so it isnt related to the kernel version.

The apport command doesnt run, it returns a command not found error, but apport IS installed.

[Tom Reynolds (tomreyn)]

Apologies, the correct command is:
   apport-collect 1837945

[Tom Reynolds (tomreyn)]

Surena: After collecting logs, please continue and report this upstream where other amdgpu bugs have already been reported:
https://bugs.freedesktop.org/buglist.cgi?product=DRI&component=DRM%2FAMDgpu&list_id=676975&resolution=---
You can file a new bug at https://bugs.freedesktop.org/enter_bug.cgi against product "DRI", component "DRM/AMDgpu".

Ubuntu bug 1818580 is possibly related - the "[drm:amdgpu_init [amdgpu]] *ERROR* VGACON disables amdgpu kernel modesetting." message was also observed here (according to details conveyed on #ubuntu IRC by user "sudo_halt" on 2019-07-25 - whom I assume is the same person as Surena Karimpour).

Sorry for late response:
Here is the command output:
Yes, i am sudo_halt!

This bug most definitely related to AMD's DC code, which i assume was updated in newer MESA versions. I will try to manually update MESA, and see if it will provide any resolution.

I ran the command you provided, and it uploaded the output to somewhere, not sure what happened.

Also, the other bugs are different: In this situation, AMDGpu's DC is the problem. Disabling it also means loss of any HDMI Audio functionality. I'll see to reporting this bug to freedesktop, if updating MESA doesn't help.

[Surena Karimpour (sudohalt)]

Updating MESA or Linux kernel does not solve the issue. I'll take this issue to AMD developers working on AMD DC support.

Thanks for your feedback. Please post a link here to the upstream bug report once you filed it.
