So I decided to do some experiments. Tried to set different max_sclk and max_mclk to see if the issue is gone. 1. max_sclk: 70000, max_mclk: 75000 --> have the same issue 2. max_sclk: 50000, max_mclk: 60000 --> pass multi-run test (more than 50 runs) [1] <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - Hang during boot when DPM is on (R9 270X)" href="show_bug.cgi?id=76490">https://bugs.freedesktop.org/show_bug.cgi?id=76490</a> "</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
