Ok, the problem no longer occurs. It seems, BIOS update did the trick after all. Strange thing is: even after the update the problem still manifested itself a few times but now it all seems good. Thank you, Christopher M. Penalver, for your help and I think you can close the bug report now.

From that point on everything seems to work as normal. Booting consistently took only a minute in Kubuntu 14.04.
