I will do that when I get back to my laptop tomorrow.

That's what I cloned and compiled this past weekend.
Two other important pieces of information are that
1) Adding nomodeset (at kernel boot/grub), the flickering is gone;
2) Using the 4.16.16-2 kernel from Debian, the flickering is not occurring
(even in absence of nomodeset).

It does happen on every boot, and within minutes the console screen is blank.
It makes the laptop pretty much unusable.</pre>
