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. -- If you say that you can't, then I shall reply, Parsley, sage, rosemary and thyme
