Oh good-one I looked over it since portupgrade was running. When I do a :

root at Riza# mount_cd9660 -v /dev/acd0 /mnt/dvd/
using starting sector 0
mount_cd9660: /dev/acd0: Input/output error

this is in dmesg:

acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x02 ascq=0x00 error=0
g_vfs_done():acd0[READ(offset=32768, length=2048)]error = 5
