Are you getting proper hotplug connect/disconnect interrupts? The driver does
exactly the same thing on hotplug interrupts. Assuming the display is active,
on disconnect it calls dpms off, on connect it calls dpms on. It also sends an
event to userspace so it's possible that may be causing a conflict. Take a
look at radeon_connector_hotplug() in radeon_connectors.c in the kernel.
