Slow system boot after tweaks

Question

yesterday I founded article on wiki about optimizations that can make my arch boot faster. So I:
disabled some of unused tty
added flags to menu.lst
disabled autoload modules in rc.conf and make load only those which were listed by hwdetect
changed mkinitcpio hooks
https://wiki.archlinux.org/index.php/Speed_Up_udev Option 3
but now I'm a little dissapointed because when arch is booting and process comes to Loading Modules it takes much much longer than whole booting process before "optimizations". How to solve it?

Answer 1

The only thing on your list that's not likely to cause these kind of complications is no. 1 - disabling unused ttys.
I would first enable module autoloading again. If the system still boots slowly after that, you can cross the module section off your list.
In that case I'd move on to the symbolic link you made for udev (option 3). Is the symlink really accurate?
If so, move on to the mkinitcpio hooks. They really shouldn't be tempered with. But just in case, this is all you need for a system with root on an ahci device using filesystem ext4:
MODULES="ahci sd_mod ext4
HOOKS="base"
It is safer to use the default though
HOOKS="base udev autodetect pata scsi sata filesystems"
If restoring the default mkinitcpio doesn't help there's only one point left on your list. Delete the kernel boot parameters.
There's also a bug in 2.6.39 related to modules ee-prom where the system would hang @ loading modules but that seems unlikely here.
P.S.:
Also, do a system update. There's a new version of udev that might or might not fix your issue.
