Subject: Re: 2.6.26-rc9-git9 doesn't boot on Macintel

YH,
   I meant that pci=nommconf doesn't allow the boot to complete
under 2.6.26. I haven't tried that under 2.6.25.10, however the
2.6.5.10 kernel should be using mmconfig since I see...

PCI: Using MMCONFIG at f0000000 - ffffffff
PCI: Using configuration type 1
ACPI: EC: EC description table is found, configuring boot EC
ACPI: EC: non-query interrupt received, switching to interrupt mode
ACPI: BIOS _OSI(Linux) query ignored via DMI
ACPI: Interpreter enabled
ACPI: (supports S0 S3 S4 S5)
ACPI: Using IOAPIC for interrupt routing
ACPI: EC: GPE = 0x17, I/O: command/status = 0x66, data = 0x62
ACPI: EC: driver started in poll mode
ACPI: PCI Root Bridge [PCI0] (0000:00)
pci 0000:00:1f.0: quirk: region 0400-047f claimed by ICH6 ACPI/GPIO/TCO
pci 0000:00:1f.0: quirk: region 0500-053f claimed by ICH6 GPIO
PCI: Transparent bridge - 0000:00:1e.0
