Someone is running pktsetup to set up a device, at boot time. The device
being passed in doesn't support pass-through commands.

I believe there are two questions here:

1) Why is pktsetup being called? I don't expect anyone to use pktcdvd
   anymore.

2) Given #1, what kind of device is being passed in?

Do  you have some ancient funky init scripts?
