--- Comment #3 from Chen Yu ([email protected]) ---
54 ms seems not that slow to me IMO, and it might not be noticed from user
experience. Since most of the time was taken during  enumerate devices in the
ACPI namespace according to the log, I assume the acpi_init() time consumed is
highly platform specific. Besides, although acpi_bus_scan() is protected by a
mutex lock, it can not be run in parallel because it is mandatory for the other 
 component.
