    Hi,

    Our customers are concerned about the following messages in `dmesg` output.

    Code:
    acpi0: reservation of 0, a0000 (3) failed
    acpi0: reservation of 100000, bff00000 (3) failed 


    The outputs of `dmesg` and `acpidump -dtv` are attached. Please help to clarify this issue.

    Or , in other direction, where to find official document to convince our customers that these messages are ignorable ?

    Try updating the BIOS of the machine. If that doesn't work you could try updating to -STABLE.

    Indeed, i am the BIOS engineer of the system. Our system got no ACPI error on Linux, but it got the above reservation failure message.

    That would explain this problem I'm having.

    Code:
    sysctl hw.acpi.thermal.tz0.temperature
    sysctl: unknown oid 'hw.acpi.thermal.tz0.temperature'
    

    _______________________________________________

    I have the same errors.
    Code:
    acpi0: reservation of 0, a0000 (3) failed
    acpi0: reservation of 100000, 7f700000 (3) failed
    

    Code:
    FreeBSD freew 9.0-RC3 FreeBSD 9.0-RC3 #0: Sun Dec  4 08:01:02 UTC 2011
