SOLVED:Kernel panic with amdcpu after blacklisting radeon

gasparov · 2017-02-15 16:23:43

Hi folks,
I'm trying to get opencl for blender so I installed opencl-amd from aur but when I run DRI_PRIME=1 blender the program closes with this message "amdgpu_device_initialize: DRM version is 2.48.0 but this driver is only compatible with 3.x.x."

I figured out that I have to blacklist the radeon driver but then when I reboot instead of starting GDM everything stuck (no caps lock, no num lock) and I think is a kernel panic. I'm not sure if this message is meaningful but here it is

My kernel is 4.9.8-1-ARCH #1 SMP PREEMPT Mon Feb 6 12:59:40 CET 2017 x86_64 GNU/Linux

Any help and directions would be appreciated

Cheers

OT: Just realized is more than 10 years I'm using arch

SOLVED: Sorry for bothering the amdgpu should be in intramfs , after this it boots. The wiki says " It is possible, however, to enable KMS during the initramfs stage" and I thought it means that it is not mandatory
