Am I asking on the right list? >Should this go to the freebsd-stable list instead? OK, further progress. I compiled the kernel yet again with the ata device commented out and the lines for the wdc device inserted. Result, everything is working, except the device name for the CD-ROM is wcd0c again -- it changed to acd0c under 3.5-STABLE. So my immediate problem is solved, but questions are still left unanswered. Where can I find out more about the ata device and why it is supposed to be better? Why doesn't the ata driver detect slave devices? Or is there some way to force it to do so? Currently GENERIC and LINT do not suggest that this might be a problem -- could some sort of suggestion, to the effect of, "If your kernel doesn't detect devices on bootup you might want to try this" be added to them? Also, I have a nagging feeling that when we were setting the system up I thought the guy in charge had the wrong jumper configuration on the CD-ROM (it was over a year ago, he's gone, and my memory is vague), but it worked so I forgot about it. Does it seem possible that the jumper configuration needs to be different to use with the ata device? Experimentation isn't convenient but a certain amount can be done on Sundays. Apparently this has not been a problem for most people upgrading to 4.x-STABLE, so how does my hardware configuration differ? Well, I may never know. -- Roger To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
