Sorry, but if you're getting an invalid IOP message then the kernel and tools
can't possibly be in sync, that's what "in sync" means in this context.

There's nothing that can happen just by adding a disk drive (unless it has some
other tools on it that appear in the PATH) that can cause this.

All I can suggest is that you download the user tools that match your kernel and
rebuild them.
