Running with the patch works fine over a vanilla kernel 3.12-rc1. The following works also fine: // if (pl->sclk > 25000) // pl->sclk = 25000; if (pl->mclk > 15000) pl->mclk = 15000; Which means sclk is working properly. However, the opposite results in a blank screen before I can even get at the login screen. It seems mclk is the problematic part.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
