Alexander Kops, couple of issues: 1) To clarify, after the firmware update, is the issue still reproducible with latest mainline? 2) Your upstream post is missing all the information requested by Intel as documented in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1727662/comments/30 . It makes it most difficult for upstream to help if the information they request isn't provided. Also, upstream may ignore your post due to it not having required, publicly documented debugging information.
