I reproduced this. Here's the interesting thing. It only started happening when I moved the disk tray from one player to another. I did not reinstall. Watching the serial port, I see the try_to_free_pages message in car mode, but not home mode. The player is in a dock the whole time.

The problem is I can't manage to run ps while it's in car mode to even see what the difference is, it destroys itself too fast.

I wonder if setting the car rate high enough that it can clear the messages will fix that.
