The system does not freeze at all (at least not for the 5 minutes since I tried it.) The second I ran echo auto > /sys/class/drm/card0/device/power_dpm_force_performance_level X froze. A rather annoying chain of bugs: 1. I have to set the refresh rate to 59.94hz to stop the screen flickering (Don't really care about this, I'd happily do this if it was the only issue) 2. It works perfectly with a single display 3. With multiple displays, setting the refresh rate to 59.94 causes the system to freeze and I have to to a hard reset 4. Points 2 and 3 are only relevant if power_dpm_force_performance_level is set to auto. This is an acceptable compromise for now. The additional temperature/power usage is far more palatable than the flickering screen or system freezes.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
