The existing message is quite confusing because it refers to FPU Emulation while most often the issue is due to either a non supported instruction (not necessarily FPU related) or a stale instruction due to HW issues. The new message tries to be more generic in order to make the user understand that the Oops is due to something wrong with an instruction, not necessarily due to an FPU instruction.
