Hi Jeff,

This looks to be a duplicate of bug 634702 so I am marking it as such for now. The Ubuntu kernel dev assigned to that bug has narrowed down a work around for the moment, ie pass in "intel_idle.max_cstate=0" at boot which will disable the intel_idle driver and fall back to acpi_idle. Please continue to use bug 634702 for any future correspondence regarding this issue. Thanks!
