Hi Ciro I was debugging the X86, mutlticore issue as suggested by you. I could see that the simulation exits as expected by changing * if (activeContexts ==0)* at https://github.com/gem5/gem5/blob/9fc9c67b4242c03f165951775be5cd0812f2a705/src/sim/syscall_emul.cc#L212 to *if (activeContexts == 1).* This change is done as per the commit https://github.com/gem5/gem5/commit/bae0edb0d26dc6c4738855cf38e9a6a109ae8003 I want to ask, whether this change ie *if (activeContexts ==0) *was a bug or intentional for some other reason?
