Comment 88 for bug 228624

On Ububunt 9.04, I switched to kernel 2.6.24-24 with solved the described problem. Now on 9.10 I see no option like this.

Is there a way out? I had no luck with all_generic_ide=1 so far:

root@cw-desktop:/home_save/cw# hdparm -d /dev/scd0

/dev/scd0:
 HDIO_GET_DMA failed: Inappropriate ioctl for device
root@cw-desktop:/home_save/cw# hdparm -i /dev/scd0

Autmount is working, but I get significant read errors:

dmesg shows:

and so on ...

It' s a bootable DVD. I have no problem to boot linux from this DVD with this drive on the same PC.
