Looks like this bug was added by 5a284cd75d635e3c5db0210dc9a9a44c6839f460 (ACPICA: Fix local variable mess in acpi_ev_asynch_execute_gpe_method). The good news is that it is new in 2.6.38-merge Also, I doubt that these error cases actually occur in any significant frequency in practice. Thanks for the find.
