That usually means the "open" method of your driver didn't succeed. For 
whatever reason, the SUNW,m64B driver returned a failure at open - 
either some allocation failed or it decided it didn't like the hardware

I've written several lines of code in C in which I am trying to access
the OpenBoot CIF to execute an instruction. But immediately after I do
the call to the CIF interface address the PROM freezes. Does anyone
have any ideas why is this so. I'm getting the CIF address from the
%o4 register passed by SILO
