Sysctl problems

[James Yates]

I am in the process of bringing up a network app with my BSP. During a
call to rtems_bsdnet_initialize, a call is made to 
sysctl_register_all. This in turn registers a oid to the head of the
list. Sysctl_register_all then calls sysctl_register_oid for 
the next in the list. On entry this assigns a pointer to the parent
which is 0xffffffff. This then immediately bombs. Has anyone
come across this problem before. I am sure that there is some
configuration problem with what I have done but I am really
stuck as to how to fix this.
 
    Any help would be gratefully received.
