Slow initialization of something during boot

[Frank]

Since I made the switch to a 64 bit machine (still using 32 bit Fedora 
19) there is a long delay just before lightdm comes up with the login 
screen.
Can someone take a look at this output and perhaps point out why and
where it's occurring ? By the way I don't use LVM or raid...can I disable
these services? What;s the best way to do that. Even so the time they 
take doesn't account for the 6-7 second delay after booting before 
lightdm comes up.

Thanks for any help
