Is anyone else having problems booting current NetBSD/sparc kernels on
   Ultra systems ?
   
   With GENERIC_SUN4U and custom kernels I get:
   
   kernel trap 10: illegal instruction
   Stopped in pid 0,1 (system) at netbsd:atomic_cas_ptr:  UNDEFINED
   db> bt
   proc0_init(...)
   main(...)
   cpu_initialize(...)
   
   AFAICT NetBSD/sparc SUN4U kernels are using the sparc atomic ops not
   the sparc64 ones.


OK, i have a patch to make this work but i need to think a little
more about how to do it properly...
