Matthew, Everything works now! I cannot thank you enough! I have been trying to debug this for many months and you solved it in less than 24 hours.

I think you are asking if I built the Linux Kernel from source. I did not build the Linux kernel from source. I installed Linux on this PC (and many others) using FedoraCore CDs and basically selecting defaults for everything. I assume that the defaults would be correct. Bad assumption? According to a colleague at Fedora, you need to add "pci=mmconf" to the kernel command line to use MMCONFIG because it was broken on too many machines. We've changed the code to not tickle the bug on these machines, so Fedora won't require this in the future. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
