I upgraded to RC2 over the weekend. This morning I came into work, had my phones browser open, and put it in my OEM dock like I do pretty much every day. I use an app called DockControl to kill the desktop dock app from running, and Setting Profiles runs a specific profile when I dock it. Normally this causes the screen to go black for less than a second (like a quick flicker). Today the screen goes black, and stays that way. A few seconds later up pops the Moto bootup icon. The phone continued through it's normally bootup sequence. Weird, eh?
