Is my boot process normal? It takes 50 seconds boot

Here's my boot.log

Here's dmesg log: http://paste.ubuntu.com/826319/'

The dmesg log shows quite a bit bump after 6 seconds, it waits too much before starting again at 24th second.

Output of fdisk -l and mount : http://paste.ubuntu.com/826397/

I have disabled almost all services which I can, but it still takes 50 seconds to boot. While booting with Live USB, it hardly takes 25 seconds.

The boot process stops for about 20 seconds at "resume libcrypt version" line. And those fscks are performed at every boot. Are those fscks necessary?

EDIT: Bootchart

Solution 1:

The normal booting time is 40s (including BIOS). You might have some "not so good" hardware which causes this problem. Also you must have kept many things on boot and installed many packages. But you need not worry.
