The only problem that I have with this PC is that my SATA HDD is being shut down _twice_ on power off (see bug 23362). It only happens if the PC has been up and running for at least an hour. If I power it off immediately (or after a short interval) after boot, the HDD is shut down correctly.

I get the same error on ASUS P8H67 rev 3.0 motherboard with BIOS version 1003. I'm using Linux 3.0-rc3.

This bugs seems to affect almost all Sandy Bridge ASUS motherboards, here's dmesg for a H61 based motherboard:

ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND (20110413/psargs-359)

I can update dmesg if advised.

It's great that the kernel bugzilla is back.

Can you please verify if the problem still exists in the latest upstream kernel?

Should I try kernel's git snapshot or Linux 'next' tree?

Patch has been shipped in upstream kernel. Bug closed.

    ACPICA: Fix to allow region arguments to reference other scopes
    
    Allow referenced objects to be in a different scope.

        Scope (_SB)

            Name (RAMB, 0xDF5A1018)
            OperationRegion (\RAMW, SystemMemory, RAMB, 0x00010000)
        }
    
    For above ASL code, we need to save scope node(\_SB) to lookup
    the argument node(\_SB.RAMB).
