Comment 96 for bug 1690085

Thanks for James Le Cuirot 2017-10-05 20:23:40 UTC. My Ryzen 5 1600 build did hang randomly with Amd drm-next-4.15-wip kernel and mainline 4.14-rc1 and rc2 and 4.13.5 custom non debug 1000Hz timer kernels. It took 3 weeks to find this solution.

X did freeze randomly when scrolling web content in the Chrome Beta browser. I thought it was usb 3.0 problem at first and moved my mouse to usb 2.0 port. Then I found help for a Chrome bug:
https://askubuntu.com/questions/765974/chrome-freeze-very-frequently-with-ubuntu-16-04
No help.

Now uptime is 7 hours and 19 minutes and system looks stable. I did enable gpu support in the Chrome again and system is not freezing while surfing.
