I don't think softintr functions take such long time (1 sec),
but it seems softintr requests are lost.
(ack after 1 sec is caused by the next ping?)

Does your port use MI mips softintr functions? (though evbmips does)
Does any inputs from serial port (which also triggers softintr)
also fix the problem?
