dmesg showing wrong frequency (IBM T30)

[Tobias Roth]

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.
