Is the CPU also pegged running cdparanoia with -Z? Also, how do you know the
CPU is pegged? If you're going by 'system load' this is not reporting CPU
usage; it's reporting 'processes running/waiting', which could easily mean that
the machine is waiting a *loong* time for the drive due to hardware trouble.
(You can use something like procmeter or MGM to see the real CPU usage).

Do you have any entries related to ATAPI or the cdrom in your system logs? You
*should*... the behavior is abnormal.
If not, run cdparanoia with SCSI hostadapter emulation. When run with the
ATAPI interface, cdparanoia cannot talk directly to the drive. The kernel
provides the command set and error handling (and does a poor job of it). With
SCSI emulation, cdparanoia talks raw packet commands to the drive and gets back
results without kernel interpretation.
