Hello,

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 ;-)

Here's what is happening:

COMPstation U2 UPA/SBus (UltraSPARC-II 296MHz), No KBD
OpenBoot 3.11, 512 MB memory installed, Serial #16009843.
