First of all, do we know where the demo precisely faults? In which heap's memset? We could then analyse how this heap is being set up in the kernel, if all mappings are done as expected, if reasonable address are passed to the user, etc. I may have my hands on a 405 board on Friday, but I'm not sure if I can do much more testing than a simple run of the program. Of course, testing will primarily take place over latest Xenomai... Roderik, you said you tested under Qemu as well? For PPC or x86 arch? Jan
