Ubuntu 15.04 is booting very slowly. I tried with dmesg output but couldn't understand which items were problems/issues actually. Here is dmesg output. Someone please help me!

EDIT 1 Here is the systemd-analyze critical-chain output. wpa_supplicant and kerneloops are killing time I guess! Any suggestion?

Okay, now my machine is booting in 30 sec. I just issued the following command:

systemctl mask systemd-udev-settle

I visualize using systemd-analyze plot > plot.svg (output) and found systemd-udev-settle to take a minute. Then masking helped me a lot.

Thank you guys for helping me out.

Yes, many people have had this same issue before. I'm positive that it is a bug in the current build of Mate. If you don't know much about code, then try another build of Mate. If the boot time is faster, then reply back.
