Considering that the error comes froom the ioctl (rather than the open)
I'm tempted to say it comes from either the vn_open() or subsequent
VOP_*() operations on the components. If you compile your kernel with
`options CCDDEBUG' and set the ccddebug variable (near the top of ccd.c
or with the ddb) to 0x03, you should be able to see where it fails. If
you could send me that information, that would be most helpful.
