--- Comment #13 from fin4478@hotmail.com --- I tested latest drm-next-4.10-wip today that have couple of more patches that yesterday. Still Xserver hangs when playing Tomb Raider Legend at full hd.
With dmesg, I have these errors at boot: [ 3.466266] amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff [ 3.466706] ATOM BIOS: C99401
[ 3.479722] [drm] amdgpu: irq initialized. [ 3.479730] Can't find requested voltage id in vdd_dep_on_sclk table!
