It's a harmless error message. I'm not sure why you're seeing it, though.
I've got code in the routine in question (dashutdown()) that explicitly
disables printing sense information if the sense key is illegal request.
Could you try the attached patch? (for src/sys/cam/scsi/scsi_da.c) It's
against -current, but hopefully it'll apply okay to your version of
scsi_da.c.
Basically, what I want to try to do is get some idea of where the above
error message is coming from... If the error message is coming from where
it shouldn't be coming from, you'll see something like this before the
above error message:
dashutdown: printing error message
Thanks,
Ken
