Sometimes we only need boot_delay to see the printk infomations. How about set it as a standalone config option? 2. In My system if I boot with boot_delay=200 the early part of booting will be very slow, eapecially at the very beginning (after the compressing and start kernel, it nearly stop here many minutes). And I wonder if we can simply use mdelay in the boot_delay_msec(). I tested the mdelay , and the result is more accurate.
