From d3493574e267c203836bfdcb9c58d8af46fc0da1 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Fri, 14 Dec 2012 16:20:46 -0500 Subject: [PATCH] drm/radeon: restore modeset late in GPU reset path Modeset path seems to conflict sometimes with the memory management leading to kernel deadlock. This move modesetting reset after GPU acceleration reset.
