I have done much testing to no avail so far. Seems like maybe something to do with ata_piix but not sure. There are so many reports across the www of people losing cdrom in relation to acpi after installing upgrades of linux. It's hard to believe there isn't an answer.
Simply put, if I disable acpi=off in the grub boot menu then the cdrom works. But it is not acceptable to turn off acpi as it is required for much of the other hardware functionality, one of which is power management that is very important when running on battery. Hope someone can point me in the right direction of something new to try. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/856253 Title: acpi issue on Lenovo3000-N200 with Ubuntu 11.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/856253/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
