Comment 28 for bug 42023

I had the same problem when trying to read from DVD-ROM (so no recordable), also at the 4GB border:

[10513.644000] attempt to access beyond end of device
[10513.644000] hdb: rw=0, want=16328340, limit=8388604
[10513.644000] Buffer I/O error on device hdb, logical block 4082084
(see complete log in attachment)

The problem vanished after stopping the packet writing tools
sudo /etc/init.d/udftools stop

So I suspect it has something to do with udftools. I also noticed that when writing DVD-RAMs with packet writing this silently fails (i.e. I do not get an I/O error at the prompt, but md5sum of written file reveals that it wasn't written correctly, there are also errors in dmesg in this case. Sorry, I don't have a log currently).
