CD/DVD reader/writer not detected in Gutsy

[Alvise Trevisan]

Hi all,

I have a Lenovo 3000 N200 laptop. I just installed Gutsy. Unfortunately, the CD/DVD writer does not seem to be detected (e.g. K3B says on startup "No CD/DVD writer found".
The releveant lines from lspci -v are:

00:1f.1 IDE interface: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 03) (prog-if 8a [Master SecP PriP])
        Subsystem: Lenovo Unknown device 3c2b
        Flags: bus master, medium devsel, latency 0, IRQ 20
        I/O ports at 01f0 [size=8]
        I/O ports at 03f4 [size=1]
        I/O ports at 0170 [size=8]
        I/O ports at 0374 [size=1]
        I/O ports at 1810 [size=16]

dmesg gives, among the other messages, the following:

[ 22.145573] PCI: If a device doesn't work, try "pci=routeirq". If it helps, post a report

It did not help...

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducable with the live environment of the Desktop CD of the development release - Hardy Heron. It would help us greatly if you could test with it so we can work on getting it fixed in the actively developed kernel. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
