Description J. Adam Hough 2007-02-21 16:29:36 UTC 
Description of problem:
When Hyper Threading is turned of in the BIOS, "ACPI Exception
(acpi_processor-0681): AE_NOT_FOUND, Processor Device is not present [20060707]"
appears /var/log/dmesg.

Version-Release number of selected component (if applicable): kernel

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
present [20060707] is reported.

Expected results:
I would expect not to see any error message stating that "Processor Device is
not present"
