I just installed RC1 of 3.5.4.1 on my c3100, on top of alpha 2. The system boots ok but when it gets to starting OPIE in 5 seconds, it clears the screen and hangs with the cursor in the top left of the screen. If I press a key during the 5 second pause and prevent OPIE trying to start all seems well. Has anyone else has any success with this configuration? If no one has anything else to add I'll just file a bug, although I'm hesitant to do that given it seems like a problem only related to RC1 and there is no specific choice for this configuration in the bug tracker.
