This bug may be a duplicate of #131094 even though I have not marked it as such (yet). See the comment at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/131094/comments/235 and test your workload against it. Note that this has been a workload sensitive problem. You may have another problem further into the I/O subsystem but eliminating this issue should be the first step, i.e. if we eliminate the I/O from VM thrashing, NCQ etc. become less of an issue. If you have further problems as indicated in earlier comments, we can then pursue potential problems in the SATA layer. Thank you.
