PCH poison interrupt
When I boot to normal boot, the X-windows display does not function,
attempts to switch to X screen with '<ctl><alt>F8' result in display of
the message '[drm:pch_irq_handler] *ERROR* PCH poison interrupt'.
When I boot to the recovery boot option, the display will only go to
1280x1024, the monitor is capable of 1920x1080 (1080p monitor).
