cpu MHz in cpuinfo is updated by cpufreq core.
So that it is not a good indication of the real frequency if cat'ing
/proc/cpufreq give what the poster said. It is more likely a bug in
cpufreq. AFAIK, there were bug, and one still remain in case of
SMP, but UP should be OK. Note also that in case of invasive patch like
aa, or preempt, for example, it may be possible that cpuinfo
entry may give bad infos.
