I've had the same thing, if your cdrecord process was in uninterruptable
sleep. If it is, there's nothing you can do about it, except reboot. Also
note, that each process in uninterruptable sleep will count as 1 in your
load average, even if it's not taking any cpu / network / disk resources.
I haven't done this myself, but you might check out the other threads about
CD writing in 2.6.8 to get some pointers about how to get cdrecord to
complete successfully. I believe you may need to specify the device. Of
course, this assumes you're using a 2.6.x kernel. If you're not, I'm not
really sure why cdrecord would hang.
Hope that helps,
