Thanks for reporting the bug and providing the logs already!
This issue looks to be much alike
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161309, would you
mind looking at comment #4 and #10 and possibly doing a few more checks?

have a clear picture whether you are hitting exactly the same issue.
Thanks!
