Yes, I indeed have done some local changes to the trinity ioctl()
support, but I have not touched the trinity SCSI ioctl stuff. I'm a
bit busy at the moment, so cannot dig any deeper into this for now.

Yes, I can see these messages in the log, here are some lines from the
console right before the WARNING:
