Well, this is what I'm doing as of today. This kernel:

[mark at Godzilla mark]$ uname -r
2.6.11-0.3.rdt.rhfc2.ccrma
[mark at Godzilla mark]$

Do this command:

rep .  /proc/irq/*/*/threaded

You'll probably see all interrupts as threaded. (The :1)

cat /proc/interrupts

and find out what interrupt your hdsp is on, then change the number to
your number and run

echo "0" > /proc/irq/9/hdsp/threaded

9 becomes whatever interrupt number YOU have. 9 is mine.

Now the hdsp is running non-threaded.

then try running Jack and see what you can do.
