Note how running "mapper" after hotplug works fine on the Force, but returns all 0xff's on the Trenton. That's where I hooked up a PCI logic analyzer and verified that *nothing* ever makes it onto the bus. This is built from jbarnes's pci-2.6.git linux-next branch about 10 minutes ago. The git commit id is at the top of the dmesg output. Thanks again for the help. If there is more debugging options I can turn on that will make this more informative, I'll be happy to do so. Ira
