So it's presumably hanging in one of: S01mountkernfs.sh S02udev S03mountdevsubfs.sh S04bootlogd i'm not sure what userspace process is causing that hang (that is, which one is being terminated when i send ctrl-c through the console), but i can try to track it down. > I assume it still doesn't actually produce sound output.
