Excellent.. seems to work now and give actually updating sensor readings :-) By the way, if you have any firmware-type contacts at Asus that know about these boards, you might want to point them at this problem, the BIOS DMAR tables point to invalid locations when Intel VT-d is enabled. So far haven't gotten any useful response from tech support.. http://www.gossamer-threads.com/lists/linux/kernel/1131574 _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
