Hello All,

I have an issue while sending/receiving data from Uart serial port using minicom. The system generated lot of hardware interrupts (1,000,000.00 per second).
I'm using Red Hat Enterprise Linux WS version 6.2.

I modified UART driver to work with our card (Exar XR16L2551 DUART). Can someone help me to debug the hardware interrupts?

Please advice.
Thanks in advance.
Amy
