Just in case it is relevant, when I upgraded to BIOS 1.18 I ran into bug #887793 (Kworker constantly taking about 100% CPU) worked around as in comment 114 there (echo "disable" > /sys/firmware/acpi/interrupts/gpe13). This suspend bug was still seen before and after the workaround. Before disabling gpe13, top showed kworker hogging one of the cores and there was no sign of Xorg near the top of the cpu usage list. After implementing the workaround Xorg re- appeared as normal with a few % of processor.
