10s sounded quite big number to me too but that is from Ville. This test
is now failing because modeset + flip take more than one second, on my
ICL box with eDP + HDMI connected it becomes 1.19s. Arek is talking
about test box where it is more than two seconds. Anyway if 10s is what
kernel is waiting in the worst case I don't think test should be more
strict.
