I have built SheepShaver from SRPM on SuSE 9.0 and ran into different problems. When I start it with JIT enabled, it won't boot:

Reading ROM file...
Illegal Instruction

When I disable JIT in prefs, it starts to boot, but while MacOS 8.1 is "Starting up...", it crashes:

Is the rom your using for sheepshaver a new world rom or an old world rom? If it is a new world you cant boot os 8.1 only 8.5-9.0.4 try using the rom from the Mac-on-linux website and use it to boot 8.5 or greater. If all you have is 8.1 you will have to extract an old world rom from some early 603 power mac.
