I am running a patched 2.6.32.20 kernel with the correct xenomai patches
(2.5.5.2 and the adeos patch for 2.6.32.20) and my RT application seems to
work fine, I can use the PEAK CAN drivers fine, and I managed to make a
config where all my interrupts work.  However, when using the machine
without any real time apps running, I start to see a lot of latency in
normal use.  Ie, a regular compile operation that normally takes a few
seconds all the sudden takes a minute, and my i/o also seems incredibly
slow.  The display also seems lag frequently.

I have been trying to track down the problem for a while now, but I am not
seeing any specific error messages in any of the syslogs or anywhere, and
the machine does not completely hang or anything.  I was wondering if anyone
had any advice on where to look next?

I'm running on a dual quad core 64 bit Xeon machine with an nvidia Quadro fx
4800, a dual channel PEAK CAN card, 2 dual channel network adapters, and a
dual channel firewire card.

For reference,  I did an install of the Ubuntu 10.04 iso, then basically
followed the instructions referenced here:
http://www.xenomai.org/index.php/Building_Debian_packages.    With the
additional caveat of doing an apt-get purge on nvidia-current and the an
apt-get install on nvidia-current to get the proprietary nvidia driver to
work with the new kernel.

Any help would be greatly appreciated.

Thanks,

Jeff Hyams
