Description Forgotten User QJZgcP9b07 2017-09-13 10:54:54 UTC 
After a fresh install the boot process stops while showing this message:

"fb: switching to amdgpudrmfb from EFI VGA"

Booting with the nomodeset option however starts X.

My system has an AMD A9-9400 processor.

Tumbleweed snapshot is openSUSE-Tumbleweed-DVD-x86_64-Snapshot20170909-Media.iso,
no additional repos enabled

It happens with xf86-video-amdgpu version 1.3 from the standard repo and also with version 1.4 from the X11:Xorg repo.

The problem didn't occur on Leap 43.2.

Comment 3 Stefan Dirsch 2017-09-13 12:02:47 UTC 
Ok. This is Stoney Ridge APU, released in June 2016, so a pretty new one. But it was already supported in Kernel 4.4 by amdgpu driver shipped on Leap 42.3. Unless 
we disabled there amdgpu driver and fell back to generic framebuffer and X fbdev driver. I guess you no longer have Leap 42.3 installed to verify this?

So this could be a regression in amdgpu KMS driver.

Please give also our kernel-of-the-day a try.

Leap 42.3 was installed until yesterday evening.


But the system indeed boots into X with the latest kernel.

So this combination works for me:

xf86-video-amdgpu 1.3.0-2.2 
kernel-default 4.13.0-2.g7e9e30a-default
Comment 6 Stefan Dirsch 2017-09-13 13:44:34 UTC 
Ok. So this sounds like a temporary regression in the kernel to me. And things will get fixed with the kernel updated in TW.
Comment 7 Stefan Dirsch 2017-10-26 20:56:26 UTC 
Ok. Let's close this one as fixed (again).
