What mess? I have two things you can try: first is running a single VCPU guest, if you have not done so already. Second is adding the bootparameter "clocksource=acpi_pm" to your guest kernel. If either of those fixes the problem, it very well have to do with this change and not that you may be missing later dependent patches. This change should be nearly a 1-1 transformation, and if it is not, something is wrong. What branch are you bisecting on, the kvm branch or the kernel tree itself? It would be helpful to see the exact code in case any surrouding logic changed. Thanks, Zach
