[PlanetCCRMA] I had time for a quick test

[Tracey Hytry]

I just got a chance to boot up one of Ingo's kernels from his yum repository.
This was done on a FC5 machine with the planet apps installed.
The machine is an athlon64@2GHz, 2gig ram, using the xorg nv video driver.
Running the 2.6.20-rc1.1.rt3.0001 kernel.

I started jack via qjackctl, using 2 periods/64 frames(2.9msec latency) using a delta 1010(ICE1712) sound card.
I then loaded up hydrogen, aeolus, and whysynth;  patching an external midi keyboard to the 2 softsynths, while hydrogen played one of it's demos.  I got no xruns while playing the keyboard at that setting, though any lower latency setting did not work.

I went and checked the interrupts and I think that the "rtirq" script might not be working with the kernel.  Below is what I got from looking at the interrupts:
