-			statement.  After system has booted up, this mask
-			can be set via /sys/module/acpi/parameters/debug_level.

-			CONFIG_ACPI_DEBUG must be enabled for this to produce
-			any output.  The number can be in decimal or prefixed
-			with 0x in hex.  Some of these options produce so much
-			output that the system is unusable.
