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
