Jussi, thanks for your helpful comments. Yes, this is definitely a product of that old memory controller problem. If you're experiencing this bug, the only solution is to find a torx T5, open the case, and disconnect the battery for a moment. This is a hardware problem more than it is a software problem.
Opening the case is fairly easy. There is a useful description with pictures here: http://www.ski- epic.com/2012_asus_zenbook_ux31_disassembly_teardown/ You don't have to remove the battery. Just pull straight up on the connector to the mainboard. There's a helpful little black pull tab for this.

Sometimes this needs couple of tries (waiting or not waiting in between) when plugin in or out AC adapter. This problem doesn't occur when I have switched to console or when in LightDM login screen. Problem doesn't happen with MS Windows either.
