>Description:


>From my kernel:      
# ATA and ATAPI devices
device          ata
device          atadisk                 # ATA disk drives
device          ataraid                 # ATA RAID drives
device          atapicd                 # ATAPI CDROM drives
device          atapifd                 # ATAPI floppy drives
options         ATA_STATIC_ID           #Static device numbering

>How-To-Repeat:
Create an iso, blank the cdrw, then burn the iso to the cdrw:

/usr/local/bin/mkisofs -UR -o /filename.iso /files-to-be-burned
/usr/sbin/burncd blank
/usr/sbin/burncd data /filename.iso fixate

Now try to mount /cdrom, and you get:
cd9660: /dev/acd0: Input/output error

Reboot, then you can mount /cdrom

>Fix:
No fix that I've found, but rebooting will allow mount and access to the disc. Burning an iso again will once more lock you out of the cdrom, requiring another reboot in order to mount it.
