Hi Ralf, nvidia prop drivers for your card never will build with new rt-kernels. I see you compile customized kernels. I'd recommend trying 2.3.36.xxx and even 2.6.37-rcxx with preempt settings. They run here on a geriatric amd64x2 machine under lucid (10.04) ubuntustudio/kx mashing with proprietary nvidia drivers, full rt support. Only missing against rt-kernels is the possibility to adjust rtirq settings which as I see *possibly* *might* give *a* *little* benefit *only* for ffado/firewire devices. Nevertheless I hope someone will implemet this rtirq tweaking stuff into mainline kernels. Regards Gerhard
