[Bug 803822] Re: DSDT: multiple errors found by fwts

[Steve Langasek]

Why are you filing this bug against Ubuntu?  Your DSDT table is part of
your BIOS - Ubuntu has nothing to do with it.

In any event, the acpi-support package is a set of scripts for handling
particular acpi events, so is certainly unrelated to your problem.

** Changed in: acpi-support (Ubuntu)
       Status: New => Invalid

       ADVICE: (for error #4122): This occurs if the length is zero and just one of the resource MIF/MAF flags are set, or the length is non-zero and resource MIF/MAF flags are both set. These are illegal combinations and need to be fixed.
       See section 6.4.3.5 Address Space Resource Descriptors of version 4.0a of the ACPI specification for more details.

       ADVICE: (for error #4117): This needs to be fixed as the length
  specified is greater than the window size specified by the Min/Max
  fields - this is clealy ambiguous.

       ADVICE: (for error #4123): A 'null descriptor' (where most fields
  are set to zero) has been found. Usually, these are updated or
  completed at run time using BufferFields, but to do so one requires a
  resource tag and this descriptor does not have one, hence it cannot be
  referenced to allow it to be updated. This is most probably a bug and
  needs to be fixed.
