Switching to console before doing the suspend is advisable.
The pm-hibernate script from pmutils will do this automatically.

If you boot with something like vga=791 you'll fit more lines
on the screen, so you should be able to capture it all.

The CD or IDE code has had some kind of accident in 2.6.13rc
it seems. I can trivially make it hang the box by feeding
it an audio CD. Sadly, its just a total hang rather than something
useful.

That you get the above msg repeatedly could be something trying
to poll the device whilst its empty (probably hal daemon).
Why its become so noisy when earlier kernels weren't is a mystery
to me right now.
