Mounting CDROMS on a cdrom/dvd/-rw used to work. At first I had a plextor 712s and thought it had
failed. I replaced it with an Optotrac and now a LITE-ON DVDRW LH-20A1L. (These are all SATA drives)

Wonder what I need to back out of lenny to get it to work again?

This was a known sata_nv problem with ATAPI devices and more than 4GB of
RAM. It should be fixed in 2.6.25.

SATA CDROM/DVD fails to mount CDROM on machine with 4G of memory

RE:http://lists.debian.org/debian-amd64/2008/04/msg00339.html

It isn't fixed in 2.6.25-2-amd64

I don't seem to be getting this into the right hands.. Can someone get me the email of the Debian
maintainer of sata_nv? I'm not sure how else to report problems with modules - I would be glad to
help test it.

It isn't fixed in 2.6.25-2-amd64 #1 SMP

This was supposed to be a fix:

I haven't seen any reports since 2.6.25. Are there updated details
(dmesg output, etc) posted anywhere?

In some cases useful info is found in syslog - try

It looks like both parties are now playing the tax Peter

A clear conscience is usually the sign of a bad memory.
