iostat -En - odd ouput for DVD drive

I'm experiencing a bit of an odd issue with a couple of servers and iostat.

host1:root> iostat -En

If I mount a DVD the problem goes away.

host1:root> mount -F hsfs -o ro /dev/dsk/c2t0d0s2 /cdrom
host1:root> iostat -En

However, as soon as I unmount the DVD the problem re-occurs.

Any ideas?
