can't mount cdrom 4.6-RELEASE

I just upgrade to 4.6-RELEASE. In the 4.5-RELEASE I was able to mount and umount my CD-R/DVD with no problems. In both versions my dmesg shows: acd0: CD-RW at ata1-master PIO4 But after the upgrade I try to mount a cd and I get # mount_cd9660 /dev/acd0c /cdrom /dev/acd0c: Device not configure
