--- Comment #1 from Bernard Fouchà <bernard.fouche@kuantic.com> 2012-02-07 10:18:29 GMT ---
Wrong diagnostic (and wrong fix, LSR must always be read before RHR).
The bug is at init time: init routine clears FIFO but do not clear Overrun
Error by reading RHR (the only way to remove the Overrun Error as stated in
NS/TI 16550D datasheet): bug isn't a LPC17XX specific bug because of this.
New bug description and patch in bug #1001475.
