--- Comment #8 from d.a.pavlov <diyan.pavlov@libero.it> ---
Closing the bug report, Reason: Not a bug
Due to a lack in documentation this issue can be mistaken for a bug.
The correct way of installing the drm drivers is the following:

required packages:
drm-kmod
gpu-firmware-amd-kmod-pitcairn (single package)
*remove packages unrelated to "Pitcairn"

/boot/loader.conf
hw.syscons.disable=3D1
kern_vty=3Dvt

/etc/rc.conf
kld_list=3D"amdgpu"
*loading the driver at RC init is the correct timing.
*do not load drivers from the bootloader or manually.

/boot/modules
delete files named i915* and radeon*
files named amdgpu must be present.

output of kldstat:
2    1 0xffffffff82400000   31fd70 amdgpu.ko
3    2 0xffffffff82320000    7f020 drm.ko
4    3 0xffffffff823a0000     cbc8 linuxkpi_gplv2.ko

driver related packages installed:
gpu-firmware-amd-kmod-pitcairn
drm-54-kmod or drm-kmod
