[SLUG] PCI bus oddity

[Phil <phil@xxxxxxxx>]

Hi

We are running a dual opteron setup, with a Tyan n6650 motherboard.  We 
need to power 4 screens so we installed dual GeForce 8600 GT cards.  
Apart from nvidia driver issues we are also seeing that the PCI bus ID 
changes between reboots for each of the graphic cards or both.

Has anyone seen this behaviour before?  If so how do we fix it?

Thanks

Phil.
