Hi Sharjeel, I think you've found another case where ARM isn't supported in Ruby. I would *guess* this is a problem with some kind of atomic/memory ordering operation. I would try simplifying your simulated system and building up until you find the problem. For instance, start with 1 core and make sure Linux boots. Then, two cores, etc. You may also want to try simpler topologies (e.g., Pt2Pt or crossbar) and using only a single directory.
This could also be a problem with the memory ranges. Ruby only supports a single range with no gaps. I don't know what the ARM systems use.
