on bug 91880
from Jan Ziak
(In reply to Ernst Sjöstrand from comment #104) > https://patchwork.freedesktop.org/series/8116/ GPU: R9 390 GPU manufacturer: Gigabyte Kernel: 4.5.5 Kernel module: radeon.ko I applied the kernel patches and let Metro Last Light benchmark run for about an hour with DPM enabled while I went shopping. Before the patch: The benchmark would lock the GPU after a while After the patch: Running OK for about an hour I checked that 'new_smc' variable in radeon/cik.c gets set to 1. ---- Remaining issues on R9 390 after the patch: Heavy screen flickering, not capturable on a screenshot. It is related to mclk transitions. Forcing mclk=1.5GHz, and letting sclk be controlled by DPM, removes the flickering. I created a new bugzilla entry related to the flickering: http://bugs.freedesktop.org/show_bug.cgi?id=96326 ---- GPU lockup in http://bugs.freedesktop.org/show_bug.cgi?id=92302 might have the same cause as this issue.
