Sometimes, I get this error message repeatedly: [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing D1FC (len 62, WS 0, PS 0) @ 0xD218 and the screen gets stuck. (last time it happened, the screen recovered by itself). The keyboard won't respond, but I can't power off the machine by pressing the power button.
