It means my EST changes work on your laptop and so est0 is attaching. The downside is that it is attaching instead of acpi_perf0, which happens to have more info about your system. It's difficult to fix this without an architecture for ordering the probe/attach of all cpufreq drivers. This is not easy since we have no general mechanism for drivers bidding for the same hardware identified by different methods. Until I can figure out a more general way, you can just set this in loader.conf: hint.est.0.disabled="1" -- Nate
