Description Alan Richter 2018-01-07 03:38:11 CET

Description of problem:
Xorg will not start if amdgpu is selected in XFdrake for the Xserver with the 4.1.4.10 kernel.

Version-Release number of selected component (if applicable):


How reproducible:
Always with the 4.14.10 kernel.

Steps to Reproduce:
1. Start XFdrake.
2. Select amdgpu for X-server.
3. reboot

If radeon.cik_support=0 admgpu.cik_support=1 is specified on the kernel command line, amdgpu comes up fine. 

Perhaps something to this effect should be added to the kernel command line when selecting radeon or amdgpu for AMD GPUs in XFdrake.

This is the same bug as https://bugs.mageia.org/show_bug.cgi?id=22284.
Different chips but with the same issue.

It can|will affect certain amd gpu.

cik (Sea Island Rx 200 series)
ci  (Southern Island HD 7000 series)

The radeon driver is the default for these cards.
For the amdgpu driver to be used appends Must be added to prevent the radeonfb
driver from being loaded and to instruct that the amdgpufb driver be used.

Thanks for the information, I should put something on the wiki instead of bothering the bugsquad.  Thanks for the response.  

Great job everyone.

This message is a reminder that Mageia 6 is end of life.

Mageia stopped maintaining and issuing updates for Mageia 6. At that time this bug will be closed as OLD (EOL).

Package Maintainer: If you wish for this bug to remain open because you plan to 
fix it in a currently maintained version, simply change the 'version' to a later 
Mageia version prior to Mageia 6's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that we cannot 
be able to fix it before Mageia 6 was end of life.
If you would still like to see this bug fixed and are able to reproduce it against a later version of Mageia, you are encouraged to click on "Version" and change it against that version of Mageia.

Although we aim to fix as many bugs as possible during every release's lifetime, 
sometimes those efforts are overtaken by events. Often a more recent Mageia 
release includes newer upstream software that fixes bugs or makes them obsolete.
