Default Re: Dual core AMD 3800+, SLI ASUS 7600 GT x2, X Windows lockup with smp kernel

The pci=nommconf kernel parameter disables the MMCONFIG PCI configuration space access method, which forces the kernel back to PCI type 1 configuration accesses. The MMCONFIG access method appears to be severely broken on a number of systems; on such systems, the NVIDIA Linux graphics driver can't reliably access the PCI configuration space of NVIDIA devices, which results in various stability problems, particularly if multi-core CPUs are used with multiple GPUs.
