There are reasons the rt-kernel developers tell us not to use the ATI
closed source driver. I suspect the problems you are seeing fall
pretty much squarely in that domain. The fglrx driver is not (as far
as we know) designed to be real-time safe. No one can tell you what
it's doing internally that might cause a time delay and kick out
Ardour, but it seems to be doing that.

I'm curious as to why are you interested in using this driver on a
platform running Ardour. Is this machine dual-purpose? I.e. - is audio
a part time thing and you also do gaming, etc.? If you must do gaming
I think you're better off to go with NVidia. I've got both here and
have fewer problems with NVidia, but that's just my experience.

Good luck,
Mark
