Thanks, it worked here but there was still lots of disk activity :<

I went so far as killing everything but network services and going into a
text console and it still ran the disk about every min. <sigh> Sitting
here normally in X without virtual-dev there is a disk io about ever 10
seconds! My poor drive :>

Would the no-atime patch help any?

Thanks,
