In the Kconfig option in the kernel.. +config BOOT_DELAY + bool "Delay each boot message by N milliseconds" + depends on DEBUG_KERNEL + help + This build option allows you to read kernel boot messages + by inserting a short delay after each one. The delay is + specified in milliseconds on the kernel command line, + using "boot_delay=N". + + It is likely that you would also need to use "lpj=M" to preset + the "loops per jiffie" value. + See a previous boot log for the "lpj" value to use for your + system, and then set "lpj=M" before setting "boot_delay=N". + NOTE: Using this option may adversely affect SMP systems. + I.e., processors other than the first one may not boot up. + BOOT_DELAY also may cause DETECT_SOFTLOCKUP to detect + what it believes to be lockup conditions.
