Stefan,
I have tested the patch series on Power8, Intel, along with ARM and
updated the bug with the test information, and the git repo I sent the
pull request from. A kernel with the patches is available in PPA
https://launchpad.net/~centriq-team/+archive/ubuntu/sru/
Could you please review and consider for SRU?
