<pre>Hi have ATI Radeon 4570 card and random white lines come all over the screen.
This problem began when i upgraded from Kernel 3.13 on linux mint and no matter
what distribution i installed (Kernel 3.16, 3.16, 4.4, 4.9) the problem
remained. Finally set radeon.dpm=0 and the problem is gone. Would like to get
this resolved. Please let me know which files to attach.</pre>
