Description Persio Barros 2007-08-01 10:14:32 UTC

Most recent kernel where this bug did not occur: 2.6.19
Distribution: Ubuntu 7.10 Gutsy (testing)
Hardware Environment: Lenovo 3000 V200 notebook
Software Environment: Linux OS
Problem Description:
After installation of Ubuntu 7.10 I noted that the CDROM was not accessible. An entry in fstab was created poiting the CDROM drive to /dev/hda. But there was no such device. I could access the drive with "modprobe ide-generic", but then I can't set DMA to the drive.
This problem happens with last kernel versions from Ubuntu (2.6.20 and 2.6.22) and also with the last official stable kernel (2.6.22.1). The problem doesn't occur with Knoppix (kernel 2.6.19). Also, Fedora 7 cannot be installed from the cdrom drive. After booting the installation system, it stops saying that it cannot find the "installation image", which is in the CD/DVD disk.

Steps to reproduce: Install a recent Linux distribution on his notebook.

What does 'modinfo ata_piix' say?

Add-a-PCI-ID-for-santa-rosa-s-PATA-controller.patch

Right, that's commit c1e6f28cc5de37dcd113b9668a185c0b9334ba8a which was added after 2.6.22 is released.  The attached patch adds PCI ID for the controller.  You've got a very new machine there.  I'll forward the patch to -stable such that it can be included in the next stable release.

Comment 7 Tejun Heo 2007-08-01 23:40:12 UTC

Closing.

Comment 8 Persio Barros 2007-08-02 04:27:33 UTC

Thank you very much for the patch. I will try it.
Can I compile only the ata_piix module or I should recompile the full kernel? In the first case, how to do that such that I can use it with the installed Gutsy kernel?

Comment 9 Tejun Heo 2007-08-02 04:30:32 UTC

You can compile only the ata_piix module if you have the exact source and config file of your running kernel.

Comment 10 Persio Barros 2007-08-02 06:14:31 UTC

It worked!
Thanks again,
Persio
