Title: Workaround (for reference): Avoid race lock up in usart

Workaround, submitted for reference: Long external interrupts may cause usart reads to lock up if they
prevent usart interrupts to be handled quick enough. This patch
increases usart interrupt priority and prevents the usart interrupt from
being delayed.
