It has nothing to do with sound at all, and the LOR between DRM device lock and send buffer socket lock is a consequence of drm activated when panic occured in the locked region. That said, first thing to do when you experience panic with vbox or fuse modules loaded, is to remove the modules and see if it happens still. If it is persistent, contact net@. I see. Problem with removing the virtualbox module is I have been able to trigger the panic only by starting the VBox VM. I have no idea how to trigger it some other way. I'll try though. Thanks for the insight! Quick followup, for any interested party, I isolated the commit in r274712, reverting this one the problem disappears. If anyone has some ideas about this please reply to me or followup in bug 195822 on bugzilla.
