With the appropriate hardware, Xenomai applications have met our requirements in terms of timing and stability. As with any product, there are sometimes problems, but the support from the developers and community are excellent. In my experience the Xenomai environment and support is on par (and sometimes exceeds) international products for which we pay ! Generally the problems that we have are with programmer interfacing with the keyboard :) < End of sales talk :) > > > In our case, no xenomai application needs to be running for the lockup > > to occur. > > Same here.

Xenomai patched kernel locks up within a few seconds / minutes. Lockup occurs after we log into the Gnome desktop. Working only in the console environment seems ok thus far. Keep well Vicki
