On my test laptop, this reduces the boot time +by 2 seconds (kernel time goes from 3.9 to 1.9 seconds). + +Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> +--- +--- a/init/do_mounts.c 2009-01-07 18:42:10.000000000 -0800 ++++ b/init/do_mounts.c 2009-01-07 18:43:02.000000000 -0800 +@@ -370,14 +370,17 @@ void __init prepare_namespace(void) + ssleep(root_delay); + } + ++#if 0 + /* + * wait for the known devices to complete their probing + * + * Note: this is a potential source of long boot delays. + * For example, it is not atypical to wait 5 seconds here + * for the touchpad of a laptop to initialize. + */ + wait_for_device_probe(); ++#endif ++ async_synchronize_full(); + + md_run_setup(); + + |
