This patch
commit c5182babd1d0706f1294af7b8dbf64e378b066bb Author: Robert Hancock <hancockr@shaw.ca> Date: Sat Jan 5 13:26:32 2008 +0100
x86: validate against ACPI motherboard resources
...
recently added to git-x86 causes one of my Intel test systems to not boot unless I specify pci=conf1.
... ACPI: EC: Look up EC in DSDT ACPI: Interpreter enabled ACPI: (supports S0 S3 S4 S5) ACPI: Using IOAPIC for interrupt routing PCI: MCFG configuration 0: base 4026531840 segment 0 buses 0 - 127 PCI: MCFG area at f0000000 reserved in ACPI motherboard resources PCI: Using MMCONFIG at f0000000 - f7ffffff ACPI: PCI Root Bridge [PCI0] (0000:00) <hang>
The system is a SDV, but I believe production level. DSDT is available at http://firstfloor.org/~andi/dsdt.dsl
On previous kernels the MCFG was rejected because it wasn't e820 reserved:
ACPI: bus type pci registered PCI: BIOS Bug: MCFG area at f0000000 is not E820-reserved PCI: Not using MMCONFIG. PCI: Using configuration type 1
Also I'm a little surprised to find my Signed-off-by on that patch.
