Comment 225 for bug 620074

Wanted to add even more testing results from my side, tried the suggestions from this source: http://stackoverflow.com/questions/392198/how-to-make-linux-gui-usable-when-lots-of-disk-activity-is-happening
by changing some vm.dirty_ variables. No improvement could be seen neither changing to deadline scheduler didn't improve the situation. I also changed /sys/block/sda/queue/nr_requests to 64 with same unresponsiveness.

i'm still on the same kernel (2.6.28-8) and my fstab mounts the partition with relatime,noatime,nodiratime flags.
