Bug description:
  {forward from James Troup}:

  Just to followup to this with a little more information, we have now
  reproduced this in the following scenarios:

   * Ubuntu kernel 4.4 (i.e. 16.04) and kernel 4.8 (i.e. HWE-Y)
   * With and without Bcache involved
   * With both XFS and ext4
   * With HIO driver versions 2.1.0-23 and 2.1.0-25
   * With HIO Firmware 640 and 650
   * With and without the following two patches
- 
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial/commit/?id=7290fa97b945c288d8dd8eb8f284b98cb495b35b
- 
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial/commit/?id=901a3142db778ddb9ed6a9000ce8e5b0f66c48ba

  In all cases, we applied the following two patches in order to get hio
  to build at all with a 4.4 or later kernel:


https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial/commit/?id=0abbb90372847caeeedeaa9db0f21e05ad8e9c74

https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial/commit/?id=a0705c5ff3d12fc31f18f5d3c8589eaaed1aa577

  We've confirmed that we can reproduce the corruption on any machine in
  Tele2's Vienna facility.

  We've confirmed that, other than 1 machine, the 'hio_info' command
  says the health is 'OK'.

  Our most common reproducer is one of two scenarios:

   a) http://paste.ubuntu.com/23405150/

   b) http://paste.ubuntu.com/23405234/

  In the last example, it's possible to see corruption faster by
  increasing the 'count' argument to dd and avoid it by lowering it.
  e.g. on the machine I'm currently testing on count=52450 doesn't
  appear to show corruption, but a count of even 53000 would show it
  immediately every time.

  I hope this helps - please let us know what further information we can
  provide to debug this problem.
