Speculations aside, I have found only one sure way of breaking the eternal kernel-hang if you make the mistake of inserting a bad CD into your drive; Needlehole eject. Sure, the kernel will spit loads of error messages at you, but atleast it wont be hung anymore, you can save work and reboot. For eternal hangs when burning CDs though, I've found the only reliable way of unhanging the system is to unplug power to the CD burner and replug it. This seems to cause some amount of disk corruption to the master device on the same IDE channel though, so I guess if you have two harddrives, like me, it is a hard choice between risking corruption on both, and risking corruption on one.
