Here's the situation... Ever since I upgraded to 2.2-STABLE, I am unable to mount any CD-ROM's that I have (I tested this by going back to the 2.2.2-RELEASE kernel and the CD-ROM worked great, unfortunately, I need 2.2-STABLE for some other fixes.) I am sure the CD-ROM is working fine and the CD is OK. When I mount the CD, it says: # mount -t cd9660 /dev/wcd0a /cdrom cd9660: /dev/wcd0a: Input/output error The drive is on the second IDE channel as a SLAVE, without a master (this worked fine before with 2.2.2-RELEASE, has there been a change?). I also double checked my source configuration files as well: controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 options ATAPI options ATAPI_STATIC device wcd0 I also have it set up for the primary controller. This is the same configuration that was in GENERIC for 2.2.2-RELEASE on my system. The drive is detected on boot up too: /kernel: wdc1: unit 1 (atapi): , removable, intr, dma, iordis I've also searched the mailing list archives, and most of the time the error is due to the device not being recognized or a CD not being in the drive, etc. However, none of that applies here. My question is: is there something in 2.2-STABLE that's changed that I would need to make other changes to my OS to make the CD work? I don't subscribe to the freebsd-questions or freebsd-stable mailing lists, so please send a copy of your reponse to me via e-mail. Thank you very much for your time, Jay jayrich@sysc.com
