I donīt know whether it was a bad mastered CD-R, or a bug in the
SCSI CD-ROM driver, but I got a media error followed by the attempt to
read past the end of the device. This was kernel 2.0.14:

Sep 5 21:05:08 elf kernel: Max size:313558 Log zone size:2048

BTW: Shouldnīt there be a blank between the "sr" and the "0b:00" in the
error message?
