My embedded board is freezing when I put E9171 on PCIe. What is the
meaning of Unrecoverable Machine Check error about GPU?
Well see the explanation on Wikipedia for example:
https://en.wikipedia.org/wiki/Machine-check_exception
In general it means you have messed up something in your hardware
configuration.
Could PCIe settings in .dts file cause this problem?
Possible, but rather unlikely. My best guess is that it is some problem
with the power supply.
If it is, is there any sample PCIe configuration for E9171?
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.

Christian.
I attached my dts file.
System is working fine when GPU is not plugged in.
