How many people use this ?? I've rarely had Linux lock up on me, but a few times I have had X lockup to the point that hitting the power switch was my only option... I think I've seen this in "make menuconfig" before. Isn't it the last selection in the menu ?? If I were to use this, I don't think you'd want to use "b" by itself, since it doesn't sync the disks. Can you use multiple selections, like "s" first and then "b" ?? Thanks in advance Hall
