on bug 91880
from Filip Brygidyn
I am experiecing the same freezes on my updated arch box (kernel 4.8.11-2, mesa 13.0.2-2) with my MSI R9 390. Without radeon.dpm=0 I observe the following: - I can get into and stay in tty with no crashes - I experience wierd filckering/'image jumping'. (Not artifacts) - With 2 monitors connected the mentioned flickering is unbearable and the image jumps so much it's hard to see anything. (and it gets worse over time) - After I start a window manager (xfce in my case) the system will freeze at the moment I cause any major load. This would support the ongoing suspition that the problem may be caused by clock or voltage changes. With radeon.dpm=0 I am yet to crash a single time in the similar way. This may be unrelated but I experience similar (although much less frequently occuring) crashes under windows. The system would run perfectly fine under load or idle for a long time but when the load is changing the system sometimes freezes or crash with a BSOD. Good example would be when I am running a game and I alt-tab a lot, changing the load drasticaly from 100% to idle and back. That is the moment when crashes occur most frequently. I am yet to try other firmware, mclk or other suggestions mentioned in here. Will post when I get enough time and motivation to tinker...
