Yes, the more, the merrier! Here is a new patch with the additional information proposed by David (and a little bit from me).On Wed, 09 Mar 2005 16:12:06 +0100, Eric Piel <[EMAIL PROTECTED]> said:

Good catch. I thought it was documented already. Perhaps it got lost. In any case, I think it would be good to mention why someone might want to turn it on. Perhaps something along the lines of:
"This increases power-consumption. On the positive side, it reduces interrupt wake-up latency, which may improve performance in certain environments such as networked servers."
please discard the previous patch and apply this one, Eric
