ichss0: transition to 1 failed

After I recompiled my kernel with device cpufreq , dmesg spits out tons of messages like:
ichss0: transition to 1 failed
What does that mean?

sysctl -a |grep ich shows:
dev.ichss.0.%desc: SpeedStep ICH
dev.ichss.0.%driver: ichss
dev.ichss.0.%parent: cpu0
dev.ichss.0.freq_settings: 1397/-1 -1/-1

sysctl dev.cpu|grep freq shows
dev.cpu.0.freq: 1397
dev.cpu.0.freq_levels: 1397/-1 1222/-1 1047/-1 873/-1 698/-1 523/-1 349/-1 174/-1

I dont use est.

My CPU: (Thinkpad R50e):
