        <div>My embedded board is freezing when I put E9171 on PCIe.
          What is the meaning of Unrecoverable Machine Check error about

    Well see the explanation on Wikipedia for example:
    <a class="moz-txt-link-freetext" href="https://en.wikipedia.org/wiki/Machine-check_exception">https://en.wikipedia.org/wiki/Machine-check_exception</a><br>
    <br>
    In general it means you have messed up something in your hardware
    configuration.<br>

        <div>Could PCIe settings in .dts file cause this problem?</div>
      </div>
    </blockquote>
    <br>
    Possible, but rather unlikely. My best guess is that it is some
    problem with the power supply.<br>

      <div dir="ltr">
        <div> If it is, is there any sample PCIe configuration for
          E9171?</div>
      </div>

    <br>
    The E9171 is just a PCIe device, so the dtsi is actually rather
    uninteresting. What we really need is a full dmesg and maybe lspci
    output would help as well.<br>
    <br>
