Subject: [PATCH] drm/radeon: restore modeset late in GPU reset path
Date: Fri, 14 Dec 2012 16:20:46 -0500	[thread overview]
Message-ID: <1355520046-4248-1-git-send-email-j.glisse@gmail.com> (raw)

From: Jerome Glisse <jglisse@redhat.com>

Modeset path seems to conflict sometimes with the memory management
leading to kernel deadlock. This move modesetting reset after GPU
acceleration reset.
