Comment 64 for bug 1791312

I've tested the kernel 4.15.0-52 (from khfeng) on my laptop and found: THE FLICKERING IS GONE!
Screen is O.K. in text and graphic - mode. Console switching works too.
So, Paul's bugfix seems to work! Many thanks!
I found one small thing:
the new radeon.ko - module identifies itself still as
"... Initialized radeon 2.50.0 20080528";
same like the buggy version.
So it is difficult to distinguish the "good" from the "buggy" - module.
