The following should fix it: diff --git a/include/acpi/platform/aclinux.h b/include/acpi/platform/aclinux.h index 624b90b34085..70b55b8fe48b 100644 --- a/include/acpi/platform/aclinux.h +++ b/include/acpi/platform/aclinux.h @@ -66,6 +66,12 @@ #define ACPI_INIT_FUNCTION __init + +/* Use a specific bugging default separate from ACPICA */ + +#undef ACPI_DEBUG_DEFAULT +#define ACPI_DEBUG_DEFAULT (ACPI_LV_INFO | ACPI_LV_REPAIR) + #ifndef CONFIG_ACPI /* External globals for __KERNEL__, stubs is needed */ @@ -82,11 +88,6 @@ #define ACPI_NO_ERROR_MESSAGES #undef ACPI_DEBUG_OUTPUT -/* Use a specific bugging default separate from ACPICA */ - -#undef ACPI_DEBUG_DEFAULT -#define ACPI_DEBUG_DEFAULT (ACPI_LV_INFO | ACPI_LV_REPAIR) - /* External interface for __KERNEL__, stub is needed */ #define ACPI_EXTERNAL_RETURN_STATUS(prototype) \
