3.20-rc0: GUI dies on resume, then systemd gots sigill

[Pavel Machek <pavel@ucw.cz>]

Hi!

In 3.19, suspend/resume was rock solid.

3.20-rc0, after resume, I could see X windows dying. So I tried to log
in on text console, but at that point got a note about SIGILL from
systemd (and dead system). syslog ilustrates it nicely.

Any ideas?
