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 ....
