dmesg partial output (full as attachment)

my senses tell me that the part below is about the cpu and if you can see seema it starts itself correctly

so i guess something in the os is preventing the cpus to exceed the 501 mhz...

how to debug this?

do you thing is possible to get any answers in this forum?

it is becoming frustrating asking to the wind, should i think atrix section has no developers?
