Yes, the downgrade fixes the signal 11 errors. I figured out that I have a lot of signal 11 error messages with systemd. With Upstart I have only 4 signal 11 errors:

[ 9.371697] lightdm-gtk-gre[2731]: unhandled signal 11 at 00000000 nip 6f4e61c4 lr 6f4e619c code 30001

With systemd, X11 starts again and again with a white screen. With Upstart I have a black screen with a blink cursor.
