TMS570: SCI Rx interrupt problem

HI Team TI,

In my design I have confgured SCI2 Rx as interrupt(code taken from halcogen).

Whenever i receive the interrupt the Intvec register is updated with 0x0000000B, which is receive interrupt index(correct one).
But the code will to address 0x00000004 and hangs there.

The baud, data length, stop, parity all are correct.

Please could any one explain why it goes to the address 0x00000004(i think its pantom interrupt address) and hangs there?

Thanks in Advance.
