Linux V 2.4.21 and earlier see the CD-ROM ok. Linux V 2.4.24 and later fail to find a CD-ROM file system. The major ide code changed since 2.4.21. I have since required the following patch in order for the kernel to see the CDROM. Enclosed is a context diff patch file. The problem appeared when I was trying to install a Slackware distribution. The bootstrap would load the kernel and initrd structure, but the kernel, once gaining control, would register file system errors when accessing the disk drive. Seeing other related SAMSUNG CD-ROM drivers in the ide-dma.c blacklist, and adding my SAMSUNG CD-ROM device to the same blacklist, and rebuilding a kernel, the problem has been overcome.
