This is because the 125MHz clock is derived from the internal PLL which seems to go into some kind of power-down mode every once in a while. The LS1028A expects a contiuous clock. Thus enable the PLL all the time. Also, the RGMII pad voltage is wrong. It was configured to 2.5V (that is the VDDH regulator). The correct voltage is 1.8V, i.e. the VDDIO regulator. This fix is for the freescale/fsl-ls1028a-kontron-sl28-var4.dts.
