Description of problem: Multisession DVDs produced by growisofs cannot be mounted on an IDE drive because of a kernel bug. The same DVDs can be mounted when the IDE drive is in ide-scsi emulation. Please fix this. Version-Release number of selected component (if applicable): Everything (afaik). How reproducible: Some documentation is found in /usr/share/doc/dvd+rw-tools-5.21.4.10.8- 4/index.html... "Linux kernel 2.6 users might experience ... http://marc.theaimsgroup.com/? l=linux-kernel&m=108827602322464&w=2 ... problems mounting multi-session media with last session starting beyond 2.2GB boundary. As fast-acting remedy I can suggest to route your unit through ide-scsi. The way it was under 2.4. Even though it's declared unsupported it actually still works in 2.6 (I for one still use it)." Steps to Reproduce: 1. Burn a DVD with over 2GB of data (growisofs -Z /dev/cdrom ...) 2. Add data (growisofs -M /dev/cdrom) 3. Attempt to mount to see the error (mount is successful with ide-scsi kernel parameter). Actual results: [root@devoi ~]# mount /dev/hdb /cdrom mount: block device /dev/hdb is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/hdb, or too many mounted file systems Additional info: I am running this test from a supported system; the system ID is: ID-1006241967.

I wasn't able to reproduce this with the latest RHEL-4 kernel. Can you confirm if this problem still exists in 4.5 kernel? Thanks
Yes, this seems to be fixed using the 2.6.9-55.ELsmp kernel.
Good. I'll close this ticket, but feel free to reopen if you manage to reproduce it again.
