Hi Jens,

I applied your patch, recompiled the kernel, rebooted and recompiled
cdparanoia without the Red Hat patches. Extracting the first track of my
test cd the result was the same as without the kernel patch with ide-cd
using the cooked interface (md5 e8319ccc20d053557578b9ca3eb368dd).

Sorry :)

Sebastian
