Hello!

I have a machine with the following processor:

CPU: Intel(R) Xeon(R) CPU           E5620  @ 2.40GHz (2400.14-MHz =
K8-class CPU)
  Origin=3D"GenuineIntel"  Id=3D0x206c2  Family=3D0x6  Model=3D0x2c  =
Stepping=3D2

When running 10.1-STABLE #5 r276908  I have:
% sysctl dev.cpu.0.freq
dev.cpu.0.freq: 2400
%

After I upgraded to 10.1-STABLE #0 r279956, this sysctl disapeared.
% sysctl dev.cpu.0.freq
sysctl: unknown oid 'dev.cpu.0.freq': No such file or directory
%

I did not change kernel config file.

What can be the cause of this problem?

Thanks.=
