Folks, If you are interested in debugging AML code, selecting a aml method to trace is useful to track down AML code problem. I have a patch filed at http://bugzilla.kernel.org/show_bug.cgi?id=6629, which enable this feature for linux. You need to echo full aml method path name to /proc/acpi/trace_method. To use on shot mode, you need to echo -n 0 > /proc/acpi/trace_flag . To use persistent mode, you need to echo -n 1 > /proc/acpi/trace_flag.
