| I attempted to load 12/23/2001 snapshot on my Tatung manufactured Ultra2
| clone and hit the infamous "Fast Data Access MMU Miss". According to FAQ
| this is caused by mismatch between ofwboot.net and kernel, but I am
| positive both were taken from the same snapshot directory. Could anybody
| help me out? I am comfortable with running prom commands if somebody
| would feed me with them ;-)

Try booting with -V.  Also do a `.trap-registers'.
