Another freeze :-( This time with `dmesg` applied after reboot, with 3.19 debug kernel, and nothing in logs. No radiotray running, no flash plugin, no multimedia playback (even in idle), no interaction (freeze during night), the only piece somewhat related to audio was VirtualBox running. I am out of ideas besides, that maybe combo ext4+lvm+encryption is faulty? This is root partition. Ok, weekend is coming, how do I disable and then reenable audio?
