--- Comment #14 from Mark Lord <[email protected]> 2010-12-30 19:52:38 --- Setting max_cstate=0 essentially disables aggressive power-saving on the CPU. So battery life will likely be reduced. Why does this help? Dunno, but it does indicate some kind of race condition in the kernel. With normal settings, operations can have higher latency as the CPU transitions from lower (slower) cstates up to cstate-0 (the fastest). Disabling cstates means the timing is always fast, and predictable.
