I am trying to investigate constant crashes I get on my Fedora 27 workstation. It is much more unstable than Fedora 26. The reason I switched to Fedora from openSuSe was instability that started occuring after fglrx driver was discontinued. I am not sure which driver is my system using. When I try "lsmod | egrep "amdgpu|radeon"", I get this:

amdgpu               1830912  0
radeon               1470464  27
i2c_algo_bit           16384  2 amdgpu,radeon
drm_kms_helper        167936  2 amdgpu,radeon
ttm                    98304  2 amdgpu,radeon
drm                   372736  30 amdgpu,radeon,ttm,drm_kms_helper

My system is using radeon but both are installed:

VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii PRO [Radeon R9 290/390] (rev 80)
    Subsystem: Gigabyte Technology Co., Ltd Device 22bd
    Kernel driver in use: radeon
    Kernel modules: radeon, amdgpu

I tried blacklisting radeon in grub, but the system loaded standard VGA instead. According to AMD my card should be compatible with amdgpu driver.

I also managed to solve the crashes by running the Gnome session on xorg instead of wayland for now.

I managed to force the amdgpu drive by adding the following line to grub:

radeon.cik_support=0 amdgpu.cik_support=1

Working fine so far.

I resolved all issues by installing Ubuntu. Rock steady. I am still running Fedora on my laptop.
