The -smp 2 hang issue is probably due to a missing PSCI v0.2 follow-up patch to QEMU, you can try: https://git.linaro.org/people/christoffer.dall/qemu-arm.git/shortlog/refs/heads/psci2-smp-fix [disclaimer: there may be a better fix somewhere on the qemu list, I haven't kept track the last couple of days] -Christoffer -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
