Thank you all, bug seems to be fixed in 4.4.74-1-default. To mark it as fixed, just one question. Now I'm getting a message during boot, causing the system to "freeze" in it during about 10-20 seconds before continuing, the message is this one: "[ 17.398977] tpm_crb MSFT0101:00: can't request region for resource [mem 0xcdb77000-0xcdb77fff]" Should I worry about it, is it related to this bug, should I file another one?
