Trenton, I too set my kernel to anticipatory scheduler and for a while i thought all was well when I ran dd if=/dev/zero of=~/test bs=1M count=1500 in order to test. Then I realized that its not a reliable testing method since the *anticipatory* can anticipate the coming zeroes that will be written. I ran dd if=/dev/zero of=~/test bs=1M count=1500 simultaniously with the one writing from dev/zero, and realized that the part of the syndrome is fixed with AS, but the problem persists...
