Fix: Don't let xmcd use direct SCSI commands. They are ugly, and are totally unnecessary under FreeBSD since the official API is the ioctl commands that are also understood by the other CD-ROM device drivers, not just SCSI only. (I appreciate that other systems are much more limited in this respect, thus xmcd uses direct SCSI commands there.) Nevertheless, you might want to search for the actual bug. This probably involves enabling SCSI_DEBUG, including syslogging to a networked machine (since the kernel printf's probably won't make it to your own disk due to the SCSI problems). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
