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.

This bug report is a follow-up of bug #8784
