Public bug reported:
This is either a resurgence of #1680904 or something close to it.
Despite running linux-generic=4.13.0.16.17 where the original issue is
supposedly fixed, I got the following error again. The effect is that X
becomes completely unresponsive while processes are running, SSH works
etc.
