After a hibernate resume cycle, the processor will not go above 1GHz. The option to go above 1GHz is still shown but doesn't work. After a reboot or a cold boot everything works as it should (i.e. upto 1.6GHz)

analyzing CPU 0:
driver: centrino
CPUs which need to switch frequency at the same time: 0
hardware limits: 600 MHz - 1.60 GHz
available frequency steps: 600 MHz, 800 MHz, 1000 MHz, 1.20 GHz, 1.40 GHz, 1.60 GHz
available cpufreq governors: conservative, userspace, ondemand, powersave, performance
current policy: frequency should be within 600 MHz and 1000 MHz. The governor "performance" may decide which speed to use within this range.
current CPU frequency is 1000 MHz.
This occurs on my Thinkpad x31 Pentium-M 1.6GHz
