I also had a problem with the xserver crashing and behaving oddly with
the intel driver, which was only curable by switching to the vesa driver.

He, so I was not the only one who got the repeating key problems with
2.6.29-rt. I think I had other issues as well.
Now if only 2.6.31-rt was out already :)

I'm using a hand compiled kernel under debian testing - 2.6.26.8 with

didn't work. (May have been my mistake but I ended up with a problem
with repeating keys and also the jack daemon wouldn't start properly.)
Will try what you've suggested and let you know how it goes.
Many thanks for the time you've spent looking into this.
cheers,

- using a program which turns the computer
keyboard into a virtual
midi device. This makes the sound much more immediate. Having
tried this, the contrast makes it obvious that there is still a
problem with delays from the edirol keyboard.
...
Watch /proc/interrupts while trying to play, and see what counters
increment in the matrix. Here's a fun way ... run this in a
terminal window while playing keys on the MIDI keyboard ...
watch -d --interval=0.1 cat /proc/interrupts
What is the kernel version? You mentioned Debian Testing and Ubuntu
Jaunty.
I use a keyboard with midi over usb and the output is
over a usb
interface, yet I haven't noticed any annoying delay. At the moment jack
is set to 16ms, which of course is more when you measure it, especially
with usb.
What distro and kernel are you using? If all else fails I'll maybe copy
your setup.
