My 1.1 don't restart when prompted via software, either by using the function through the Apple menu > restart or after some software update / installation where it is necessary to restart. When prompted to reboot it gets stuck with the entire black screen, so I need to hold the power button for a few moments, and turn it back on.
I need to resolve this for Yosefix work properly and be able to upgrade my system, does anyone have a solution?

Mac Pro 1.1 / 20gb Ram / gtx680 / Yosemite 10.10
 
I have the exact same issue with my Mac Pro 1,1 flash to 2,1 running El Cap latest release. Ive even got a flashed 8800 for the boot screen and I still cant ever get it to do a proper restart
