Without installing, updating or removing any software, I am 
experimenting with kernels 4.9.0-4-amd64 and 4.9.0-3-amd64.

When I applied the Debian 9.3 upgrade, it installed a new kernel and 
retained the older kernel. I can select the newer or older kernel using 
the advanced boot menu.

When I boot with the newer 4.9.0-4-amd64 kernel, I experience the 
problem with screen going black for 1 second. This happens sporadically, 
but often enough to disrupt normal workstation activities.

When I boot with the older 4.9.0-3-amd64 kernel, I am not able to 
duplicate the problem.

I only discovered how to boot between old and new kernels last night, so 
I am going to continue booting on the older 4.9.0-3-amd64 kernel until a 
new kernel is released. I will post to this bug report again ONLY IF I 
discover that the problem occurs using the older 4.9.0-3-amd64 kernel.

I believe that the Debian 9.3 upgrade and/or newer 4.9.0-4-amd64 kernel 
introduced a problem that causes my screen to sporadically go black for 
1 second. The general conditions to duplicate this problem are outlined 
in my previous posts to this bug report. The simple diagnostics about my 
machine, which I provided as attachments, are also available in previous 

Thank you.
