I now tested with 3.15-rc3-utopic and the problem persists. I can't ssh into the laptop after coming back from resume, looks like it is frozen. Also I don't know if versions of Kubuntu older than 13.10 work as I didn't have the laptop before. I will attach dmesg and Xorg log from a running system before suspend. After that I will work on info from comment #6
