Hello, We need someone with a x86 Mac that didn't boot with 2.6.18rc2 or earlier without applying patches. We got one report of this, but the original reporter isn't answering anymore. Can you please add the attached patches to 2.6.18rc6 and report if your system boots now? Patch order is pci-probe-type1-first i386-acpi-mcfg-check acpi-mcfg-check remove-mcfg-dmi Thank you, -Andi
