I posted on this before, and I'm confirming that the problem is still happening at Problem started with 2.6.15*. Saw it again in 2.6.16. If I reboot into 2.6.13, I still see some cdrom and/or scsi errors, but the system does not freeze. This was from running grip on a music cd. It also happens just reading most burned cd's or dvd's.

Problem drive is Toshiba DVD-ROM SD-M1401 (scsi). I do not see any errors with the same media in a Yamaha CRW2100S (scsi burner).
