Hi Dave, I'd just been reading about problems with early AMD chipsets. So far I've not determined if mine is in the broken or working list. I've also been looking at ohci-hub.c and ohci-pci.c. I'm open to suggestions for sections of code to focus on and/or snippets to test. "lspci -vv" output is attached. Now to search for AMD's errata docs. Thanks, David
