Now and then, I can find a cd that'll mount, but most won't. Have tried the ones that won't mount on this obsd box with atapi instead of scsi & no problems. Googled around and searched the archives for the error messages, but didn't find anything to help so far. Read the man page on camcontrol and the warning about using it, so checking with the list before I do anything else. I did find one thing through google about the scsi delay sometimes needing to be increased, and I made that change in my kernconf before recompiling, but it didn't help. Tried booting with kernel.debug just to see what would happen, and it went smoothly, but this time there was no error message in dmesg, except that it said there was no medium present, which wasn't true. There was disk 1 of fbsd 5.5 install in the drive. When I try to mount a cd, I get `cd9660: /dev/cd: Input/output error' or sometimes, `device not configured'. Another thing that confuses me is, I thought in /dev, besides cd0, that there would be devices like on my obsd box, i.e., cd0a, cd0c, rcd0a, rcd0c, and so forth. The only cd entry in my fbsd /dev is cd0. I read some on MAKEDEV and saw that in fbsd 5, it's deprecated, replaced by devfs. I thought maybe somehow, from some of my earlier upgrades, that I had screwed up something with devices being created. Below is some info I've gotten that I hoped would help.
