Comment= # 2 on bug 96326<= /a> from Jan Ziak 
The flickering disappears after switching from X11 to Linux co=
nsole
(Ctrl+Alt+F1) and back (Ctrl+Alt+F7). mclk transitions 150MHz <-> 150=
0MHz 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 f=
or
the fix.
