amdgpu kernel module fails to load on kernel 5.4.5-0-lts (Exec format error)
When trying to start GDM on my desktop with a Radeon RX Vega 64 graphics card, Xorg fails to start up, and /var/log/gdm/greeter.log
shows the line:
(II) AMDGPU(0): [KMS] drm report modesetting isn't supported.
Checking lspci -v
shows that the amdgpu module hadn't been loaded, and running modprobe amdgpu
produces the following output:
modprobe: ERROR: could not insert 'amdgpu': Invalid argument
Attempting to force insertion with modprobe -f amdgpu
produces the following output:
modprobe: ERROR: could not insert 'amdgpu': Exec format error
System information:

was installed -
amdgpu
Xorg driver manually specified in Xorg configuration (it was initially not autodetected by Xorg), and driver loads successfully per/var/log/gdm/greeter.log
-
gnome
,gnome-apps
, and all dependencies installed and updated to the latest version in the 3.11 repositories as of 11:09 UTC December 24, 2019 - CPU is an Intel i5-4690, GPU is an AMD Radeon RX Vega 64
Xorg and the kernel driver both work perfectly fine with on Slackware-current, which also uses the 5.4.x kernel series.
Please let me know if I need to provide any other information.
