Description of problem:
created large iso image 1.4G using mkisofs. Attempt to burn image with cdrecord
using command cdrecord -v -eject dev=0,0,0 -sao <iso filename>. Burning completes
successfully, however when attempting to copy the contents of the disk i receive io errors after 580 - 600Meg. Attempt several times to confirm error. All attempts are consistent. 
Reboot the machine and load 2.6.9-5.EL kernel and repeat process. Burn completes dsuccessfully and copy completes successfully.

Version-Release number of selected component (if applicable):
cdrecord-2.01.1-5 & kernel-2.6.9-22.EL

How reproducible:

Steps to Reproduce:
1. using 2.6.9-22.EL make large iso image (over 1 gb) burn to dvd media
2. Mount dvd media
3. copy contents off of disk to fs
  

Actual Results:  cp fails read data off of media after approx. 580 - 600MB

Expected Results:  All data should be recoverable from dvd media

This request was evaluated by Red Hat Engineering for inclusion in a Red
Hat Enterprise Linux maintenance release.

As this bug has been in NEEDINFO for an extended period of time we are going
to close this bug due to inactivity. If you would like to persue this
matter feel free to reopen this bug and attach the needed information.

With the goal of minimizing risk of change for deployed systems, and in
response to customer and partner requirements, Red Hat takes a conservative
approach when evaluating enhancements for inclusion in maintenance updates
for currently deployed products. The primary objectives of update releases
are to enable new hardware platform support and to resolve critical
defects.

However, Red Hat will further review this request for potential inclusion
in future major releases of Red Hat Enterprise Linux.
