Kernel Bug Tracker – Bug 5392
Copying the RefOf reference to Named object spoils that reference
Last modified: 2006-09-28 13:15:57 UTC
Most recent kernel where this bug did not occur:
The Linux kernel ACPI interpreter fails the following
AML test when it is compiled into a simulator. So if an
OEM BIOS includes this code, Linux would fail.
Steps to reproduce:
Run interpreter with the .asl demo code attached below.
Created attachment 6254 [details]
ASL code to reproduce bug.
Two the same methods are represented by demo.
The only that differs Method m001 from method m000
is that RefOf reference in m001 is copied to Named
object but not to LocalX as it is in m000. Method
m001 unexpectedly causes exception.
