Hi,

Nothing is wrong. This is a thermal protection mode that use P 4 Molbile
processors, this means that when there is nothing to do the processor
works at 1,2Ghz according to your cpu, try to do some workout for youer
system, then check your processor frequency

Subject: dmesg showing wrong frequency (IBM T30)

Hi

On my IBM T30 1.8GHz, dmesg (with both 4.8 and 5.1) shows me this line:

CPU: Intel(R) Pentium(R) 4 Mobile CPU 1.8GHz (1196.13-MHz 686-class CPU)

Various windows utilities also claim that the cpu identification string
marks my cpu as 1.8 GHz unit, while the maximum frequency always gets
detected as something just below 1.2GHz.

What is wrong here? To other IBM T30 users: Is your CPU identification
correct?

thanks, t.
