Hi, looks like SMP in emulation mode is broken once --enable-io-thread is turned on. Linux SMP guests lock up early during boot, often the whole QEMU process becomes uncontrollable after a while. That's at least the case here with x86 targets. The problem disappears when using -enable-kvm or building without --enable-io-thread.
It's not on my critical path (ie. no time to go into details), I just stumbled over it and wanted to drop a note. Jan -- Siemens AG, Corporate Technology, CT T DE IT 1 Corporate Competence Center Embedded Linux
