My B132 (which works 2.4.0) crashes sometime between palo launching the
kernel, and it having a working console (serial).  That is to say, no info
at all.  If someone wants the machine in order to debug it, just holler...

Backtracing is extremely straight-forward, and can be automated, AFAIK.
Walking the stack forward is a bit more challenging, but not entirely
beyond possibility most of the time...
