Divide Error culprit found

Greetings,

My system was never too happy about the kernel versions > 2.1.109
(or so) ... and it seems that I found the culprit. All versions
since about 2.1.115 did not boot up and ended with a divide error
in do_fast_gettimeoffset. I had my system set to overclock to 233 mhz,
where my cpus are 200mmx cpus. I always had doubt about the cpus truely
running both at 233 mhz because the bogomips reported for both cpus (who
are identical according to sspec number) were differing by quite some
degree (the one 400+ the other at 390+, which was exactly the same value
of the one cpu not overclocked). Some people however assured me that
my fears were nonsense - yet it seems I was right after all. But okay,
it was my fault to overclock my system against my fears and it
didn't boot up because of the rather 'unhealthy' overclocking
however older development kernel versions did. So my question is,
(sorry if this is a RTFM or way too newbiish question, yet it interests
me) has the cpu handling become so aggressive that the tolerance
decreased? So that my system which was once able to boot up development
kernels when overclocked is no longer able to do so?

I'd be happy about any input,
- Chris
