The kernel source has scripts/show_delta to see the relative times between lines of dmesg. That combined with the initcall_debug arg you're already using should go some way toward helping you find where the boot is slow. Then there are a variety of tools you can use to drill down further if necessary, with the simplest being some extra printk's in the kernel paths that the output points you to if you're willing to do that. You might also do some more runs to see if your numbers are stable. thanks, Daniel
