Comment 41 for bug 1727662

As reported upstream, when I used the drm-tip kernel I didn't see the FIFO error message in the logs again (but still had random power downs).
I'm running the mainline kernel 4.15.0-041500rc8-generic and also don't see any of the described issues anymore (although I still have 1-2 random shutdowns per week while the notebook sits in the dock unattended, but there is currently no hint that it's related to the Intel driver).
