SRU Justification:
Impact: On reboot or shutdown the current Xen code does try to stop other CPUs. However the IPI communication is disabled already at that point. So issuing a reboot or shutdown from within an instance with multiple vcpus hangs.
Fix: Cherry pick of an upstream patch (added around 2.6.37) removes the attempt to stop other CPUs.
Testcase: From within an EC2 instance, call "sudo reboot". Instance never comes up again. With the patch applied it does. |
