It looks to me that flow-control is disabled, is that right? Not only does uart(4) make use of the larger buffer of the hardware, it's also more efficient under puc(4) than sio(4) is because of the use of the serdev I/F. It's possible that the receiver can not keep up when uart(4) is used. A serial line analyzer should tell you more...
