  Thank you.  I can rebuild everything with DEBUG_FLAGS=-g.  But do I need to do that in only boot?

  And, that message says:

  But, I'm not sure what "the boot monitor prompt" refers to, where i'm supposed to enter "ctrace".  When the boot crashes, I'm left at the open prom.  Is that where I'm supposed to enter "ctrace"?  Apologies if so, I just haven't known of that OBP command previously.

  Thank you.  I'll try to come up with the debugging output you're requesting.  And more directions would be appreciated.
