Guys,
That was my suspect i.e. my board is bad, but I have tried same JLINK with other board from ATMEL -- AT91SAM7 series , result is same. I have same trouble. Infect my colleague who has another JLINK, has same issue ...also . He spent 3 days worth of time to find out this issue.... since every time you cycle power, the program can break in the interrupt, otherwise, can not break in the interrupt when there is a breakpoint in interrupt routine.
I do not think it is the issue with my phytech or Atmel board from my colleague.
More like a issue with JLINK.

That sounds like a hardware fault. Either with the board or the
J-link. It's acting as if the reset from the J-link is trying to pull it
down but can't sink enough current. Either the pullup on the reset is too
strong or the reset on the J-Link is not able to sink reasonable current or
there's a bad ground connection or ....
