--- Comment #8 from Mike Lothian mike@fireburn.co.uk --- Hmm, I notice these errors:
[ 2.050887] [drm:radeon_acpi_init [radeon]] Call to ATCS verify_interface failed: -5 [ 2.050994] [drm:radeon_acpi_init [radeon]] Call to ATIF verify_interface failed: -5
which I think are ACPI calls, it might be worth checking your BIOS/EFI is up to date and if that doesn't fix things maybe play around with the acpi_osi= options
