--- Comment #172 from MAD adamczuk@tlen.pl --- Created attachment 135239 --> https://bugs.freedesktop.org/attachment.cgi?id=135239&action=edit journalctl_amdgpu_4.14.0-041400rc7
I've had more luck with amdgpu. Well kinda. It finally boots without nomodeset (starting from 4.13 kernel). But falls back to software rendering (Device: llvmpipe). It also complains that: amdgpu 0000:01:00.0: SI support provided by radeon. amdgpu 0000:01:00.0: Use radeon.si_support=0 amdgpu.si_support=1 to override.
But when I start it with: modprobe.blacklist=radeon radeon.si_support=0 amdgpu.si_support=1
screen freezes, gnome doesn't start and it produces output from attachment. Something about "dead whales": lis 04 19:35:39 pc gnome-session-binary[1369]: CRITICAL: We failed, but the fail whale is dead. Sorry....
There is also something about: lis 04 19:34:09 pc org.gnome.Shell.desktop[1440]: amdgpu_device_initialize: Cannot parse ASIC IDs, 0xffffffea./usr/share/libdrm/amdgpu.ids: No such file or directory
