In this  case  you  should  post  your  question  /  problem  on  the
rtai at rtai.org mailing list instead.

Seems you are using the wrong kernel  source  tree;  the  patch  name
"D2002-09-26"  suggests  that  you  should use the kernel source tree
version from date 2002-09-26.

Obviously you have mis-configured your kernel. You try  to  access  a
non-existent device (standard serial port?).

Just follow the instructions in ftp://ftp.denx.de/pub/RTAI/README
