Hi Dashi,
Thank you for your report ,but this seems to be kernel from RedHat 7.2 not our latest one nor stable, so I am not sure how many people here may be interested in your issue. If you don't get answer you can talk to RH support. Also this kernel is not the latest  available for 7.2 so you may just try to update it.

Thanks,
Lukas
