I can confirm this. I've attached my syslog before the lock-up. Interestingly, it has this line in the middle:
alsa-util.c: snd_pcm_avail() returned a value that is exceptionally large: 862552 bytes (4889 ms). pulseaudio[2079]: [alsa-sink-CX20585 Analog] alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. I pkill -9'd the pulseaudio process, but it continued freezing again after the process respawned. ** Attachment added: "Extract of syslog" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1074968/+attachment/3924413/+files/syslog-extract.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074968 Title: Pulseaudio leading to rtkit making hard kernel lock-up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1074968/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
