Matt must not have tested the BDR functionality in camcontrol or > something...hmm. Well, try the attached patch for cam_xpt.c. Well, I just tried it out. It does send a BDR to the device, but it looks like there's some bogus behavior. The camcontrol process gets stuck in 'cbwait', so either the CCB isn't getting done(), or the queue is not getting un-frozen. My guess is that the queue is still frozen, since I can't send a TUR to the disk, and I/O times out. Ahh well, more bugs to fix.
