Hi, all Now my device needs 2 minutes to boot up. But I found that the booting time will be reduced to 1 minute after I add just a printk(..) invoking as shown below. Even though the booting time has been reduced by adding one line of routine,but I have not found the real reason why the device needs 2 minutes to boot up.
Do you have any ideas or suggestions on my question? /linux2.6.29/init/main.c static void __init do_initcalls(void) { initcall_t *call; for (call = __early_initcall_end; call < __initcall_end; call++){ do_one_initcall(*call); printk("yangwd, do it,0x%x\r\n",call); // just add this line of routine } /* Make sure there is no pending stuff from the initcall sequence */ flush_scheduled_work(); } Thanks Gary -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
