Sandy / Ivy is not affected by reboot bug because intel did not release fix for V2 for them which is responsible (with one exception). Our business Kabylake-U is affected. You just did not notice yet. Our business Broadwell-U managed to do quite a few funny things since patching. Occasional restart/freeze/iGPU data corruption... But we have large number of devices, so opportunity to see issues is several magnitudes greater. Secondly, inability to confirm something whot has been confirmed is really not important.
