Thread: No CD burner after kernel upgrade

    No CD burner after kernel upgrade


    I did a hdd install of Knoppix 3.1 and the cd burner (liteon 52x24x52x) worked fine using the 2.4.20-xfs kernel. The burner was scd0 under /dev.

    But when I upgraded my kernel to 2.4.21, the burner doesn't work, I cannot even read from it or write to it. I have tried to read lots of different cds, ones which used to work.

    root@box:/# mount /dev/scd0 /cdrom
    mount: /dev/scd0 is not a valid block device

    root@box:/# mount /dev/hdd /cdrom
    mount: /dev/hdd: can't read superblock

    root@box:/# ls -al /dev/cdrom
    lrwxrwxrwx 1 root root 3 Aug 16 23:54 /dev/cdrom -> sr0

    root@box:/# ls -al /dev/hdd
    brw-rw---- 1 root disk 22, 64 Apr 15 2001 /dev/hdd

    I think i have to re-run some program which will fix this, but I don't know what. I have never set up a burner under linux before.

    Try editing /etc/lilo.conf and changing the append line so that hdd=scsi is hdd=ide-scsi then run /sbin/lilo and reboot and see if this helps.
