[Bug 432178] Re: [CX700] Mouse, keyboard, and power button freeze

[captinkid]

As posted by GNET13001, the error seems to stem from the CPU min freq. A
kernel patch or the following change used on the Acer Aspire one will
get it running without the crashing.

Oh, almost forgot, don't remove cpufrequtils. These application are responsible to prolong your battery charge by downclocking (thus preserve electricity) within processor. Normally you have an "ondemand" setting which may throttle processing power up and down.
