there is no bogomips or mhz....

Last time, i add 'BogoMIPS' field in cpu_speed(), and update to v0.5.4, because i see it in your previous issue #23 . Could you print the output of cat /proc/cpuinfo ?

Actually those servers got updated during Christmas...

Looking at kernel sources...

Ping?

@FillZpp any news here?

[FillZpp]

@ignatenkobrain How about this #40
