I tried to do something really similar to your commandline: qemu -enable-kvm -kernel kernel-build/arch/x86/boot/bzImage -append "root=/dev/sda1 debug sched_debug ignore_loglevel sysrq_always_enabled console=ttyS0" -hda systemd.img -serial stdio -m 1G -vnc :0 This boots up properly here, I can login using root/root from vnc. qemu -enable-kvm -kernel kernel-build/arch/x86/boot/bzImage -append "root=/dev/sda1 debug sched_debug ignore_loglevel sysrq_always_enabled console=ttyS0 init=/bin/systemd" -hda systemd.img -serial stdio -m 1G -vnc :0 ^ Only init=/bin/systemd added, and this results in a panic in most cases. I'm attaching the stdout of qemu, showing the fail in put_prev_task_fair. $ qemu -version QEMU emulator version 0.13.0, Copyright (c) 2003-2008 Fabrice Bellard kernel-build is a git build using the config I already sent and after a 'git checkout v2.6.36'. I can try to build master as well, so far what I saw is that the bug occurs there as well, but less frequently, so maybe that's a bit harder to debug. I also want to note that - at least on my machine - if I drop -enable-kvm the bug is hard to reproduce, maybe that's because that way it does not trigger a race condition or my machine is just too slow without kvm and it triggers some timeout, changing the behaviour; I'm not exactly sure. (But again, I can reproduce the bug on real hardware, so I don't think we have a kvm bug here.) Thanks, Miklos
