/usr/lib/modules/4.16.5-1-kasan/kernel/drivers/gpu/drm/amd/amdgpu/amdgpu.ko:
ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV),
BuildID[sha1]=fa6433331b1f8048ce1c9b487d7b67d7a4aa4c31, not stripped

It does not say "with debug_info", so I'm compiling a new kernel with
CONFIG_DEBUG_INFO and CONFIG_DEBUG_INFO_REDUCED activated. I will post the
results as soon as I have them.
