Re: SLI not working, X log says "Trouble accessing PCI Config Space"
Same exact problem here using ASUS Sabertooth X58 with Xonar sound card and two GTX-285 cards with bridge installed. Worked fine in Ubuntu 10.04 with 195 drivers. Works fine in Windows 7. Ubuntu 11.04 was a fresh install and NVidia 270 is working fine except for SLI. Identical Xorg.log display as well...
