Thanks for the tip! I loaded linuxkpi, drm first, and then tried to load ra=
deonkms with the following results:

[drm] Initialized
link_elf_obj: symbol acpi_get_table undefined
linker_load_file: Unsupported file type

I see a protoype for this function (and others) in sys/compat/linuxkpi/comm=
on/include/acpi/acpifx.h:494. Perhaps all of them are missing? Can we add a=
 linker script or something similar?

Anindya

Correct. It's almost certainly missing symbols. To find out what they are w=
ithout crashing your system, load linuxkpi, then load drm, and *then* load =
radeon. Note that if your hardware is SI or newer it's supported by amdgpu.
