To make it even more strange - As I reported earlier, on kernel 4.2.3 my system was unusable. I've downgraded to LTS kernel 4.1.12 and had not a single issue since than. I'm running 4.1.12 sucessufully for more than a week now - not a single freeze. I don't even need any pstate=disable command args any more, which was necessary on 4.2.3 to survive more than few minutes. I haven't tested 4.1.10 though.
