Comments? > I committed Julian's CDROM changes for him so I bear some responsibility for this but I don't have a CD-ROM drive on the FreeBSD system at the moment. Is this happening to everyone with a CDROM with the new code, or only with this media vision device? "scsi_probedev" tosses out a "be silent!" TEST UNIT READY before doing the inquiry specifically in order to catch these power up issues. Apparently this device isn't complaining through a TEST UNIT READY or INQUIRY and finally complains when we do a READ CD CAPACITY. I just looked at the diffs that I applied for Julian and I don't see where the new behavior was introduced. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
