I've got a muxed system with intel+radeon graphics card. If I switch off the device, unload the radeon module and reload it I get the following errors and can't use the device until I restart the system: [ 108.234152] [drm:r600_ring_test] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xFFFFFFFF) [ 108.234199] radeon 0000:02:00.0: disabling GPU acceleration [ 113.249241] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [ 113.249286] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E192 (len 2328, WS 4, PS 4) @ 0xE7E8 ... snip ...
