29     * Bug 298:
30     *
31     * SUMMARY: AcpiExOpcode_XA_XT_XR routines assign addresses of released cache objects to WalkState->ResultObj causing further problems
32     *
33     * Note: appearance of bug greatly depends on the memory cache dynamics
34     *
35     *       So, PASS of this test doesn't mean yet that the root cause of the problem
36     *       has been resolved.
