I think your board is being held in reset by something other then the J-link
dongle.  If the board is in reset and the jlink device can't free it, your
will get the problem you described.  You can prove that by taking your
working board and holding the reset button down while you start the openocd.
It will break 100% of the time too.

Have you looked at your board reset signals on a scope?
