Description Bill Nottingham 2011-02-11 21:35:26 UTC 
Description of problem:

If a machine has multiple PCI domains, the PIRQ fallback code can lead to false positives, since it ignores them.

The following systems in beaker have multiple PCI domains.

dell-pet710-01.lab.bos.redhat.com
dell-pet710-02.lab.bos.redhat.com
dell-pem905-01.rhts.eng.bos.redhat.com
dell-per905-01.rhts.eng.bos.redhat.com
dell-pem805-01.rhts.eng.bos.redhat.com

Comment 6 Shyam Iyer 2011-02-16 16:31:47 UTC 
Actually.. I had like to clarify..

Although the Dell systems that I mentioned here(and they are the only ones) have multiple PCI domains they would all have SMBIOS version 2.6 so you will not default to the PIRQ fallback code for these sytems as they would have the SMBIOS provided names.

I am not sure if there are other OEMs that have a situation where they support a system with multiple PCI domains and don't provide SMBIOS names. 

This fix will help such other OEM systems.
