I tested with another video card (GeForce 8400 GS), and suspend works normally.

But if I resume my computer right away after it was suspended, it resumes properly. I occur this problem if some amount of time passed between suspend and resume. And I didn't reproduce this problem when lightdm was stopped (but the screen is black after resume, but I can login via SSH). But with launched X Server the problem occurs both with nouveau and Nvidia proprietary driver. There is not this problem on Ubuntu 14.04 (it is installed on this computer too but without madm and root partition encryption).
