My ASUS U38DT performs suspend (after closing lid or choosin option) only once after reboot.
Second time at the same session suspend doesn't happen.

Before re-installation from 14.04 with 3.13 kernel everything worked fine. Now I have clean installation 14.04.2 with 3.16 kernel I have this problem.

have you solved this problem? I had exactly the same issue on my laptop when I installed Ubuntu 14.10
I tracked it down to a bug in the kernel, at least in my case. Try using my kernel see if it fixes it. Suspend has been working with no issues for me for about a week now so I'll push the change upstream when I have a chance.
