I'm having issues since the last kernel upgrade on my Cherrytrail tablet, not sure if it's the kernel or possible mesa-related. Need to dig into it some more. Booting normally just stalls after showing a couple of console messages (about when GDM would normally show up). Booting in rescue mode and then exiting out sometimes works, sometimes not. But then screen rotation is broken and stuck in portrait mode (I guess iio-sensor-proxy was started before the driver was ready in that case). It also seems flaky and usually the GUI locks up after a while also when booting up this way.
