Description of problem:
When Hyper Threading is turned of in the BIOS, "ACPI Exception

appears /var/log/dmesg.

How reproducible:
Reboot and it will print the message

Steps to Reproduce:
1.Boot with Hyperthreading disabled in BIOS

  
Actual results:
ACPI Exception (acpi_processor-0681): AE_NOT_FOUND, Processor Device is not
