Cdparanoia stuck in blk_execute_rq

I'm running Fedora Core 3 with kernel 2.6.9-1.667smp.  Whenever I'm
running cdparanoia to rip a CD track, and there's a problem, the
cdparanoia process goes into an uninterruptible sleep.  "ps" shows
that it's stuck in blk_execute_rq.  So far I have
only managed to kill the process by restarting my machine.
