Hi Jouni,

Commenting the lines did fix my UART 3 issue, but I am not clear as  
to what is happening by having it enabled. Before I dig in further  
can you give your thoughts as to why these lines could result in  
UART3 hang?

I've had these lines commented out for some weeks now and still get  
the hang.




Thanks.

Regards,
Khasim
