We make a customized carrier board and use Intel 8265NGW as wifi module.
We find that sometimes the system has pcie errors. This pcie error rate is about 1/20.
We also test the jetson nano developer kit. This error is also happended.
But the error rate is lower than our carrier board. It is about 1/60.
How can I solve this problem? Any suggestions would be greatly appreciated.

Please also share the error message. Thanks.
Please share kernel logs which has these PCIe error and also “sudo lspci -vvv” output.
also, can you please give the output of “sudo lspci -vv”? If you see ASPM enabled for the link between root port and the WiFi device, please add “pcie_aspm=off” to the kernel command line and check.
Receiver error most likely caused by L0s. You can disable aspm runtime with below command, give it a try.
echo “performance” > /sys/module/pcie_aspm/parameters/policy
I tested these two different solutions.
One is to add “pcie_aspm = off” to the kernel command line, and the other is “pcie_aspm.policy = performance”.
Both of them can solve this problem. Thanks for your help.
Also, are there any side effects of using these two solutions?
There are no side effects, apart from increase in power consumption.
