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
