Thanks both of you for replying, but that's not the problem.  (YES, it
dose go away when stopping “cdparanoia” error-correction reading
functionality, but that's for a good reason (read down) and it's not the
solution!)

The problem is in the native IDE interface in the stock Ubuntu Kernel
when reading “sub-channel” (for error-correcting, which used by
“cdparanoia”).

You don't face this problem if you're using the IDE-SCSI emulation
interface even when turning “cdparanoia” level to the maximum.  Here are
some links about the subject:
