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. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/
