>Description:
Using cdparanoia (via ripit), causes a panic when it attempts to
rip a data track.  Is cdparanoia doing something bad or is this
really a kernel bug?

I've seen this bug with two different CDs, and it appears to have
occured with RELENG_4 both now, and as far back as at least July
2003.
