<pre>The flickering disappears after switching from X11 to Linux console
(Ctrl+Alt+F1) and back (Ctrl+Alt+F7). mclk transitions 150MHz <-> 1500MHz no
longer cause monitor flickering after that.
The code in the Linux kernel executed during the switch to Linux console and
back fixes the issue, we just need to pinpoint the code lines responsible for
the fix.</pre>
