I had been testing 2.5.2-pre11 and earlier, but hadn't looked at reading from my cdrom for a while. Yesterday I created examined several large cdrom sets that had been readable earlier and they read partially but get read errors. These same cdroms can be read reliable on 2.4.18-pre3 using the same hardware, and are readable on other PC's runing older kernels.
Has anyone else seen cdrom read errors with 2.5.2-pre* kernels?
Using 2.5.2-pre11
# mount /cdrom && md5sum /cdrom/* md5sum: /cdrom/dcd-c.tar.gz: I/O error md5sum: /cdrom/dcd-d.tar.gz: I/O error
An example of some of the messages were

errors repeated with sector and blocks increasing by 4 repeating 118 times
using 2.4.18-pre3 I get no errors
