You could compile a kernel with the DEBUG and DIAGNOSTIC options to  
see if anything trips up. Are you able to break into the kernel  
debugger by issuing a BREAK on the serial console?

Just out of curiosity, can you still ping the machine, but not connect to it?

Are you still using the G130? If so, could you try doing the build  
over the on-board SEEQ interface instead? If that fails as well, is it  
possible to attempt a local pkgsrc build?

Sorry for the late response -- I've been busy and was hoping that  
someone more knowledgeable would pipe up.
