Suggested link showed me that I should run sudo apt-get upgrade -s command and it stated that I shouldn't see upgradeable packages, but I did see. Then, I unchecked trusty-proposed packages and updated the listed packages. It revealed that a window asks for a password for disable uefi secure boot during the update. I suppose, I missed that window during the previous update, or it was somehow hidden since I did't notice it. Leaving secure boot enabled may have prevented the loading of closed sourced drivers (maybe wireless and touchpad in my case). I disabled secure boot using this prompt, and now I can see a temporary screen during ubuntu boot with "booting in insecure mode". New kernel (3.13.0-92-generic) loads fine, wireless and touchpad works now as expected. Secure boot in computer's original "BIOS" is seems to be left enabled, so I can still boot Windows 8 as well without problems. This issue can be closed.
