I've a IDE ATAPI x10 cdrom drive. When i had Red Hat Linux 5.2 installed it worked fine. When i tried to install Red Hat Linux 6.0 it hangs during installation. I had to copy it to my hard disk to install it properly. Once installed, when i tried to access the cdrom, it gives 'lost interrupt' error, after that, i can't unmount it, so when i shut down the system, the cd can't be unmounted and i have to turn off the machine. The same cd's that worked fine with Red Hat 5.2, did not work properly with 6.0. I think the kernel isn't the problem because in Red Hat 5.2 i was using version 2.2.8 and with Red Hat 6.0 the same kernel didn't work.
This cannot in any way be a problem with the dev package. 6.1 has a newer kernel and it might be worth trying its install disks to see if they can read from the CD. (You can't use the 6.1 install disks to install 6.0, though.)

If this is still occuring with 6.2 please re-open
