My Do not disturb icon stays in the status bar. I tried to tap on it in Quick Settings but it didn't change. So far, I have boot in Safe mode, wipe the cache partition and didn't fix. I'm about to do factory reset but I'm not sure about the new backup/restore in the A9 (you can no longer backup to HTC). I don't worry about loosing the content but I don't want to spend hours to reinstall my apps and re-arrange them.
