Take into account that an RTAI hal patch must be applied to an original 
kernel, from www.kernel.org, having its very same version, not to the 
kernel that comes with your distribution.
Have you care of that?
To be clearer, I've PC with an old DEBIAN/Linux 5.0 (Feb. 2009), with 
Linux 2.6.26-2-686, on which i run the latest RTAI, from vulcano, using 
Linux-4.4.43.
