How is the system initialized on your platform? Do you run the x86 system bios in an emulator? There are some suspicious messages in your dmesg log: [ 0.542968] radeon 0000:01:05.0: BAR 6: can't assign [??? 0x00000000 flags 0x0] (bogus alignment) [ 0.542968] [drm] No integrated system info for your GPU, using safe default [ 0.542968] [drm] Unsupported IGP table: 1 4 The system bios is responsible for a certain amount of the gfx initialization on the IGP chips. The sbios sets up the reserved window of vram at the top of system ram and it is also responsible for patching certain vbios data tables, notably the IntegratedSystemInfo table which has platform specific information about your IGP setup that the driver needs for certain things.
