I have a Gigabyte GA-890FXA-UD5 motherboard.  I have opened a support
ticket with Gigabyte but have not yet received any reply.  The
virtualization option in the BIOS is turned on, there do not appear to
be any other relevant options.  

$ lspci -d 1002:5a23
$ ls /sys/firmware/acpi/tables/
APIC  DSDT  dynamic  FACP  FACS  HPET  MATS  MCFG  SSDT  TAMG

If there is any response from Gigabyte to AMD can it be published on
the list please?

Thanks
