Hey, est seems to be happy now!

coretemp0: <CPU On-Die Thermal Sensors> on cpu0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
coretemp1: <CPU On-Die Thermal Sensors> on cpu1
est1: <Enhanced SpeedStep Frequency Control> on cpu1
p4tcc1: <CPU Frequency Thermal Control> on cpu1

Even C2 and C3 are anounced.

dev.cpu.0.cx_supported: C1/20 C2/40 C3/60
dev.cpu.0.cx_lowest: C3
dev.cpu.0.cx_usage: 0.09% 2.48% 97.41% last 207us

But the system behaves strange. The fan comes up 10 times a minute and for 
example "sh /etc/rc autoboot" runs 5 minutes now. Load is too high without 
any processes running. And rebooting takes a long time syncing buffers. Are 
these side effects known?

acpidump output did not change.
