Description Robert Moore 2007-09-25 10:11:38 UTC 
Alias operator does not work properly with objects that open a scope. These objects can have child objects and these objects cannot be seen via the alias. Objects include Scope, Device, Power, Processor, and Thermal.

The alias is expected to perform exactly as the target.

any update about the fix, Bob?
Comment 4 Robert Moore 2007-10-23 08:38:32 UTC 
Fix was released in version 20071019:

Fixed a problem with the Alias operator when the target of the alias is a named ASL operator that opens a new scope -- Scope, Device, PowerResource, Processor, and ThermalZone. In these cases, any children of the original operator could not be accessed via the alias, potentially causing unexpected AE_NOT_FOUND exceptions. (BZ 9067)
Comment 5 Lin Ming 2007-11-07 23:03:47 UTC 
It's fixed in ACPICA-v20071019.

We can close it now.

Comment 7 Len Brown 2008-06-13 21:15:35 UTC
