Motorola PowerStack II / Estrella 300 and options FIRMWORKSBUGS

[Jochen Kunz <jkunz%unixag-kl.fh-kl.de@localhost>]

Hi. 

1. If any developer in Germany (Europe) wants to get a machine like this
contact me off-list. I may be able to get 10 of them for about 20..30
EUR each (+ shipping). 

2. I am trying to get ofppc-current to run on my Motorola PowerStack II
(aka Bull Estrella 300). 1.6 runs more or less. (Single user shell
crashes.)
With the current kernel the machine hangs after printing 

NetBSD does not yet support the "MOT,PowerStack_II_Pro4000".
Using generic OpenFirmware driver support.

I thought about the good old printf debugging, but I found a document at
docs.sun.com describing the use of OpenFirmWare for low level debugging.
So I wrote a small sh/awk script that extracts C-function names from
source files and looks up the address via nm in netbsd.gdb. So it is
easy to set breakpoints in the OFW, "load net" the kernel and stepping
with "go" from breakpoint to breakpoint. When it hangs and doesn't get
to the next breakpoint I know closer where to start putting printfs into
the source.

This was the theory. In practice the kernel prints as usual its "NetBSD
does not yet"... 
when I "load net" and "go" without breakpoints, but hangs immediately
when I set any breakpoints at functions from e.g. ofppc/machdep.c

Is this is a firmware bug or am I completely wrong and it is not
possible to use OFW debugging functionality to debug a NetBSD kernel? 

As speaking of firmware bugs: Is there any document on "options
FIRMWORKSBUGS"?
