dmesg

Hello,

I've been using Alex's linux amd-staging-4.11 tree for a bit, but a certain commit makes it unusable for me:

commit	70b696cc1961fca375f4eeb649df90d17016fc52
drm/amdgpu: Add module param to control SI support

With this commit, the display stops getting updated during boot, and based on dmesg sddm crashes. The system is still responsive and seems to work fine apart from the display when I tried using it from SSH.

I've attached the dmesg.

I am using a 280X so SI.

I'm on Arch Linux 64b, up to date.

Maybe my configuration needs to change after this commit, I'm happy to try anything.

Thanks!

[    3.750697] amdgpu 0000:01:00.0: SI support provided by radeon.
[    3.750698] amdgpu 0000:01:00.0: Use radeon.si_support=0 amdgpu.si_support=1 to override.

You'll need to follow this suggestion.

Oooooops, sorry about that.

And thank you for the quick reply!
