I compile GENERIC or variant thereof with amd support, the thing
crashes.  The trace output is below.  

Also, would anyone be kind enough to tell me what some of this means?  I'm
aware that these are the functions on the stack, an inkling that the
problem is in apm_set_var in param.c.  Is this right?  I've had precious
little ddb experience.  What would I do next?  Whoever figures this out,
can I walk through your head and see how you troubleshoot this?  I have
had C experience, just nothing with the debuggers.

Thanks,
