[LinuxBIOS] PCI Bridge Parity Errors

Hello,
Can someone direct me to some good sources where I can find out how to  
diagnos parity errors in Linux? I NEED to find out why my PCI Bridge  
has a unclearable parity error. Funny thing, when I Google lspci  
82801DB all the PCI Bridges have the Detected Parity Error bit set??  
Status: <PERR+
Does that make any sense??

Thanks - Joe
