Kernel 2.6.32-49 hangs at reboot (though not halt) when run under a Xen PV guest. Our hypervisor is XenServer 6.0 with all the latest packages.

If we revert to 2.6.32-48, the problem goes away and reboots are successful.

This suggests a regression introduced in -49, possibly this patch (though I am not certain):

  * kernel/sys.c: call disable_nonboot_cpus() in kernel_restart()
