OK.  Is the input corruption at the beginning of the pasted buffer, or the 
middle?  And this is with CPUIdle enabled?

With CPUIdle disabled here, what I thought was output corruption occurs in 
the middle of the pasted buffer occasionally.  But it might be input 
corruption, if the CPU manages to empty the RX FIFO while the TX FIFO is 
empty.
