Public bug reported:
My CD/DVD drive was working fine and detected in feisty just after
install with the 2.6.20-12 kernel on amd64 intel santarosa platform
(vaio vgn-fz11m), and after installing the updated 2.6.20-16 kernel, it
doesn't work, when i go back and boot from the old kernel, there it is
again. It's an scsi-based cd/dvd in a pretty new laptop, I've tried
every kernel switch at boot that I could find around the internet even
vaguely relating to this problem to no avail. It manifests by saying
Unable to mount the selected volume. mount: special device /dev/hda
does not exist
I've tried with:
noapic nolapic acpi=off pci=routeirq pci=noacpi acpi=noirq pci=nomsi acpi=force
irqpoll all-generic-ide insmod=ide-generic
libata.atapi_enabled=1
For whatever it's worth, I've tried all of these in various
combinations, they all seem to impare the speed of my machine and have
no other effect. There's nothing in /dev folder, no cdrom, no hda, no
scd0, no sda, no ide or anything CD-Related, just my four partitions on
my harddrive.
I would have gone back to using the old kernel, but I can't reinstall
the restricted modules as they have been removed from the repositories.
Any help with this would be greatly appreciated, I've spent a painfully
long time on google trying to solve this one and have got nowhere.
Thanks!
