I think the key information is the error returned during device_attach.
A return value of 6 is ENXIO (device not configured).
est0: <Enhanced SpeedStep Frequency Control> on cpu0
est: CPU supports Enhanced Speedstep, but is not recognized.
est: cpu_vendor GenuineIntel, msr 6160f2506000925
device_attach: est0 attach returned 6
The reporter also noted SpeedStep was disabled by the BIOS.
