I think that may be a bug. I see that if you have an XPT_CONT_TARGET_IO CCB, for an INQUIRY, as you would in your case, it would be CAM_DIR_IN, but would need to copy the data from userland into the kernel.

I have CCed Alexander Motin, he originally wrote that change and can take a look at it. > > > > Hiroki Mori Thanks, Ken -- Kenneth Merry ken@FreeBSD.ORG
