Or should I file PR? The controller in question is a Promise Ultra100 TX2. The error message comes from sys/cam/scsi/scsi_cd.c, in function cddone(). The logic is a little hard for me to follow (I understand about 70% of it). Look at lines 1724 to 1877 for stable/9. 1. Can you provide full output from a verbose boot when the CD/DVD drive is attached to the Promise controller? 2. What firmware version the card is using? The PDC20268 had many, many firmware problems relating to ATAPI devices. 3. I wouldn't worry about ATA66 vs. ATA33; this drive can only support up to about 22MBytes/second so ATA66 isn't going to get you anything, so as a workaround, using the PIIX4 for it would not hurt you. 4. ONLY if this turns out to be a "controller thing": I'm not sure how much effort should be spent trying to make this work, as the PDC20268 is legacy/deprecated hardware (made/released 13 years ago). -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Mountain View, CA, US | | Making life hard for others since 1977.
