This is definitely not a bug. On my machine, I get 119 instead of 120 about every 20th time I read /proc/cpuinfo. Does your harddrive run because of some other process while doing this?
I thought about reading the clock speed once at bootup and save the value. But that would provoke horribly machine-dependent code in ./init/main.c
Cheers, Stephan
