Andy: Could you try compiling the latest kernel from drm-next-4.3-wip? I've been running it all day without a single lock up, before it used to lock up several times a day. Just wanted someone to confirm if it is in fact working, or if it's just me.

I can imaging that it's far better for desktop locks - I moved onto it when it got updated.

Initially testing with Unigine Valley I thought it was going to be good - I got further than ever before (about 4x through all the scenes having not got through once previously), but it did lock.
