Is your Sil card running the latest base bios? If not, why? That's the one meant for optical drives, not the RAID bios.
I never had any problem with my 216 running on a Sil 3512 (which is basically the same thing).
So anyway, you've got drivers issues somewhere along the line, the patin couffin ones are just low level enough to bypass the issue I guess. It's not really a fix though to use them, more just a workaround.
The logs you provided just show you burning rubbish media - RITEK-S04-66.
Do you have any where you've been burning decent stuff and it's failed?
