I've installed Xenomai 2.0.1 but can't load a module stack for the vxWorks
skin. Kernel is 2.6.13 with the included ipipe patch and I'm getting the
following results.

# insmod xeno_hal.ko
# insmod xeno_nucleus.ko
# insmod xeno_vxworks.ko
# insmod xeno_uvm.ko
insmod: error inserting 'xeno_uvm.ko': -1 Function not implemented

# insmod xeno_hal.ko
# insmod xeno_nucleus.ko
# insmod xeno_uvm.ko
# insmod xeno_vxworks.ko
insmod: error inserting 'xeno_vxworks.ko': -1 Device or resource busy

I've put some printk's into the nucleus modules and found that in the first
case there are two pointers which are compared when a subsequent modules is
loaded. Those pointers are expected to be equal but are unequal and the
module is rejected. Can someone tell what I can do here? Maybe there is
something wrong with the modules, with the distro (Suse 9.3) or maybe I'm
doing something wrong. I think i'm gonna try the original gnu modutils next
and get rid of that Suse stuff.

regards,
Hans
