All, I was getting exactly this same error following a fresh 8.1 load Sep 25 07:51:22 cyborg kernel: acd0: FAILURE - READ_BIG ILLEGAL REQUEST asc=0x64 ascq=0x00 Sep 25 07:51:22 cyborg kernel: (cd0:ata1:0:0:0): READ(10). CDB: 28 0 0 0 0 0 0 0 40 0 Sep 25 07:51:22 cyborg kernel: (cd0:ata1:0:0:0): CAM status: SCSI Status Error Sep 25 07:51:22 cyborg kernel: (cd0:ata1:0:0:0): SCSI status: Check Condition Sep 25 07:51:22 cyborg kernel: (cd0:ata1:0:0:0): SCSI sense: ILLEGAL REQUEST asc:64,0 (Illegal mode for this track) Sep 25 07:51:22 cyborg kernel: (cd0:ata1:0:0:0): cddone: got error 0x6 back the solution was explained in the gnome install FAQ - here is a clip - the devfs.conf changes fixed the problem. To figure out which CD/DVD drive you will be using, run the following command as root: # camcontrol devlist Your output will look similar to the following: <QSI CDRW/DVD SBW-242 UD22> at scbus1 target 0 lun 0 (cd0,pass0) The devices in parentheses at the end are important. You must make sure the /dev entries for those devices are writable by the users that will be using brasero, totem, rhythmbox, or sound-juicer. In addition to those devices, /dev/xpt* must also be writable to your brasero, totem, rhythmbox, and sound-juicer users. The following /etc/devfs.conf configuration will achieve the desired results given the above devlist: perm cd0 0666 perm xpt0 0666 perm pass0 0666 Nick
