It was frozen and totally unresponsive. To be precise, the last time it happened (from that log), the widget it was stuck on was completely locked up after that - it didn't continue rotating through widgets, and that one didn't even continue playing. It was the Chuck Norris Facts widget and it stayed on the one about Chuck Norris being a vegetarian for something like 5 minutes
However, as I watched the log, I saw that it still noticed every time I mashed the button. It would rotate through a series of messages each time I pushed it, and after I hit it like 10 times in a row, the control panel finally did come up.
Curiously, I wasn't playing any music at all on it during that session. Just playing widgets and pulling up the SSH and USB shell for show-n-tell. Curiously, on a reboot prior to that one, when I plugged in my USB keyboard, it did switch to shell mode, but the shell was blank! Just a black screen. Unplugging the keyboard left the black screen up. That was kinda embarrassing
edit: And yes, this is with the original power adapter! (LOL)
