Ubuntu – Slow boot after clean install of Natty


The time have risen from 20-25 sec in Meerkat to 35 sec in Natty. I do not know if it is ureadahead but made a bugreport of it in launchpad. I tried Fedora shortly before installing Natty. They use systemd instead of upstart and didn't have this slow boot.

In a dmesg this jump shows up:

[    3.087606] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
[   15.292831] <30>udev[308]: starting version 167

How could it be that booting got so much worse? I also have a "black screen" much longer before Plymouth splash starts in Natty then in Meerkat. Could it be the famous kernel regression?

I set ACPI=off in grub... it worked :)

It boots in about 30 second (before that 2-3 minutes).
