the bug seems to be independent of the other bug (gpu hangs). i activated sna acceleration as pointed out in comment #75 of the other bug, but the system crash happened again (while listening to internet radio) without any gpu-hang in the logs.
After hard reset i found this in syslog: pulseaudio[2739]: [alsa-sink] alsa-util.c: snd_pcm_avail() gab einen Wert zurück, der außerordentlich groß ist: 3487192 Byte (19768 ms). pulseaudio[2739]: [alsa-sink] alsa-util.c: Dies ist höchstwahrscheinlich ein Fehler im ALSA-Treiber »snd_hda_intel«.
