Think I might have found the answer in est(4): ### est: CPU supports Enhanced Speedstep, but is not recognized. est: cpu_vendor GenuineIntel, msr 471c471c0600471c device_attach: est%d attach returned 6 Indicates all attempts to attach to this interface have failed. This usually indicates an improper BIOS setting restricting O/S control of the CPU speeds. Consult your BIOS documentation for more details. ### so the next problem is out-of-band access, so not a freebsd problem. Sorry for the noise. --
