Description of problem: Fedora 23 do not play nice with a Dell Inspiron 5447 laptop. This laptop have hybrid graphics (i915 and amdgpu) and looks like the support for the ATI card is buggy.
Version-Release number of selected component (if applicable):
Latest kernel package of Fedora 23.
Just boot the system and check dmesg.
There are some errors when starting the discrete card, both modules are loaded. I can't disable the discrete card (as vgaswitcheroo is not disponible), my system is overheating (fans are always active).
Boot without glitches and I will can disable the card using /sys/kernel/debug/vgaswitcheroo/switch.
lspci and dmesg attached.
