Sadly, I pushed the card a bit harder with Serious Sam 3 and it hanged again. So I'll try two different things: - keep spread spectrum disabled only for mclk but reapplying both patches from <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - Display freezes after login with kernel 3.11.0-rc5 on Cayman with dpm=1" href="show_bug.cgi?id=68235">bug 68235</a>; - disable all spread spectrum without reapplying the other two patches.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
