I'm using R4 with the latest upsampling updates. (which works great BTW) I'm using a USB serial port adapter that I have had for a very long time, so everybody has drivers for it. The difference was that the computer the adapter is plugged into was powered down over night, the only thing I can think of is that the reboot reset the adapter and somehow that changed the behavior. The strange thing was that it DID work yesterday, but only after I first logged in with SSH. I powered up the wandboard and the different swamp boards multiple times and got the same behavior yesterday. They are all working fine with boot messages today. I can debug fine today so unless it happens again there is no need to worry about it. I don't think too many people are using the serial port.
