Yes. I'm sorry I missed that. I enabled it, but it still doesn't work.
Some timeouts are occurring when I try to mount the CD-ROM. The CD-ROM
works fine with the old IDE framework. Here's the dmesg errors that
occur with libata and scsi cdrom support:

Oh, forgot to include the CD-ROM detection part. Are those abnormal
status errors a red flag?
