Hi,

I noticed a problem with CPU freq in 7.1-STABLE. The maximum frequency 
showed by sysctl is 500Mhz lower than what it should be for my Pentium M 
2Ghz.

Here is the output from dmesg:

and the output from sysctl:
dev.cpu.0.freq_levels: 1500/-1 1312/-1 1200/-1 1050/-1 1000/-1 875/-1 
800/-1 700/-1 600/-1 525/-1 450/-1 375/-1 300/-1 225/-1 150/-1 75/-1
dev.est.0.freq_settings: 1500/-1 1200/-1 1000/-1 800/-1 600/-1

This used to work correctly in 7.0...

Thanks!
