Subject: 2.6.18-rc6-mm2 ACPI and MCFG errors
I'm seeing some ACPI errors from 2.6.18-rc6-mm2 that I didn't see in
2.6.17-based kernels. This is on an Asus A8N-SLI Deluxe with the latest
BIOS. Not sure what exactly these are indicating, but they don't seem good:
ACPI Error (evregion-0317): No handler for Region [BRCR]
(ffff81007df8e960) [PCI_Config] [20060707]
ACPI Error (exfldio-0290): Region PCI_Config(2) has no handler [20060707]
ACPI Error (psparse-0537): Method parse/execution failed
[\_SB_.PCI0.MBIO._CRS] (Node ffff81007df96d50), AE_NOT_EXIST
ACPI Error (uteval-0212): Method execution failed [\_SB_.PCI0.MBIO._CRS]
(Node ffff81007df96d50), AE_NOT_EXIST
As well I am also seeing this:
PCI: BIOS Bug: MCFG area at e0000000 not reserved in ACPI
In 2.6.17 it would seem to use MCFG without complaint or problem. It
seems the check was changed to checking whether it is reserved in the
e820 tables to checking whether it is reserved in ACPI. On this system
it appears it is reserved in e820 tables but not in ACPI. Maybe it could
check if it was reserved in either one?
Full dmesg is attached.
