I haven't approached that yet, but I just noticed, having been booted to this for all of 5 minutes, that although I told it not to renice x when my script ran 'make oldconfig', and I answered n, but there it is, sitting at -19 according to htop. The .config says otherwise: [root@coyote linux-2.6.21-rc7-CFS-v5]# grep RENICE .config # CONFIG_RENICE_X is not set So v5 reniced X in spite of the 'no' setting. Although I hadn't noticed it, one way or the other, I just set it (X) back to the default -1 so that I'm comparing the same apples when I do compare. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
