dmesg
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.
