I'm having really slow boot times. I don't know what's going on with my computer, I did a fresh install of Ubuntu 12.04.2 and my boot time is really slow. How can I speed it up?

This is the boot chart. BootChart

My computer specs:

Lenovo IdeaPad U310 
Intel core i5-3317U - 1.7 GHz (2.6 GHz max freq)
500GB HDD - 5400RPM 
Intel® HD 4000 (integrated)

Add your /var/log/syslog – psusi Jun 29 '13 at 22:52

Something seems to be wrong with your sata controller and it doesn't want to reset properly. Try adding libata.force=nohrst to your kernel command line in /etc/default/grub, and run sudo update-grub to make it take effect on the next boot.

Should I Leave the kernel option set for future reboots or leave it there indefinitely? – Victor Alejandro Martinez Jun 30 '13 at 0:16
