Description petr.m 2016-10-24 09:28:02 UTC 
Signal on HDMI output disappear during boot on my computer(mb ASUS AT3IONT-I, Opensuse Tumbleweed minimal server) after upgrade kernel to 4.8.3-1-default (64bit).
I can see message "loading initial ramdisk ..." after then blinking cursor in the corner for a few seconds and after that the screen goes to black and monitor gives me message "no signal".

I blacklisted nouveau kernel module for getting video signal.
It's enough for me.
