drm/radeon: Always flush the VM 2013-05-11T20:54:07+00:00 Jerome Glisse jglisse@redhat.com 2013-04-16T16:20:15+00:00 4a0efa7ea15f619003b9ac58f9c2313bd98282dd commit 466476dfdcafbb4286ffa232a3a792731b9dc852 upstream. This is slightly cleaned up version of Jerome's patch. There seems to be an issue tracking the last flush of the VM which results in hangs in certain cases when VM is used.
