Exception handlers and interrupt

Hi All,

        i went through this link


and related a53 vector table implementation.

in this regard, i have a question

1. Say a processor gets stuck in exception handler due to one of the exceptions, would it still respond to hardware interrupts?

   in other words, say a processor is in exception handler function and it gets an UART interrupt, will the UART ISR gets invoked and be able to service the request.

so the reason i am asking this question is to recover a board which is landing into exception handler and send all its REGISTERS/STATE information via UART directed to console.
