I managed to get no xruns while recording, and some xruns when using virual instruments like setBfree (which I like very much). I only use vanilla kernels with threadirq and I assign high priority to the card interrupt. The machine is sandy bridge with core i7 processor and 8GB ram.

About the Focusrite, Johannes Kroll is right the meter was removed from the kernel driver (I don't know why). I was speaking about the internal mixer, which can mix hardware inputs and computer outputs to the hardware outputs of the card. I use Ardour internal meter to check the input signals, I think the lack of hardware metering is not a problem IMHO.
