The user is reporting an issue when using the '-cpu haswell' option with NetBSD on QEMU-2.9.0. They mentioned that additional CPUs aren't initializing properly because the application processor enters x86_pause() and never returns. + +x86_pause() consists of 'pause;' followed by 'ret;'. The user found that replacing this with two nops fixes the issue but without pause, which is needed for spin loops. Also, using '-cpu phenom' works but the system seems confused about the CPU type. + +So, looking at possible categories: It's related to x86 instruction handling in QEMU. Since the problem occurs during assembly lowering (how 'pause' is translated), it's likely an issue with the code generation or translation from the target architecture to machine code. The category 'assembly' seems appropriate here because it involves incorrect behavior of a specific instruction, leading to a hang. +</think> + +The bug is related to how the x86_PAUSE instruction is handled during assembly lowering in QEMU when using the Haswell CPU configuration.
