In ACPICA, we found an issue where the _CRS r= eturns an extended IRQ descriptor, but it gets optimized to an IRQNoFlags d= escriptor before the template is sent to _SRS. This causes problems on some= machines. We fixed this and actually made a clarification to the ACPI spec= ification that the _SRS template buffer must contain identical descriptors = as returned from the _CRS template. This change was made in ACPICA version = 20080213. BZ 9487 is the Linux sighting. 13 February 2008. Summary of changes for version 20080213: Fixed a problem where resource descriptor size optimization could cause a=20 problem when a _CRS resource template is passed to a _SRS method. The _SRS= =20 resource template must use the same descriptors (with the same size) as=20 returned from _CRS. This change affects the following resource descriptors:= =20 IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri.
