Hi,
I'm seeing around 2 s "lost" during kernel boot, that are not
accounted for any init call (excerpt of dmesg with initcall_debug
follows, kernel is 2.6.29).
What's the suggested way to investigate such problems?
Thanks,
Corrado

I take it you don't have an initrd ?
If so I know what you are hitting; I have a patch to solve it but it's
a bit convoluted and not ready for mainline.... let me know if you want
to try it, I suspect it'll solve your issue ;)

You guessed right.

Sure. I'd like to test it.

They worked fine. With fastboot enabled + some ACPI patch that alexei
is working on, I can now boot the kernel in 1.7s.
