I'm running my box for 5+ hours right now with your patch applied in addition to Andi's/Milan's patch (http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-crypt-scale-to-multiple-CPUs.patch) , Ted, and can't see any indications of corruptions so far (while doing an emerge -e system) and doing everyday stuff. My /home partition (with ext4) is also still intact [which of course has a backup] so it seems to fix it for me, too so the corruption I was seeing was similar in a way to that of Jon You can add a Tested-by: Matthias Bayer <jackdachef@xxxxxxxxx> Thanks a lot to everyone for your support ! :) I have a question though: the deactivation of multiple page-io submission support most likely only would affect bigger systems or also desktop systems (like mine) ?
