Pcieport 0004:00:00.0: AER: can't find device of ID0000

Hi
I’m using a custom Orin NX board and it occasionally reports ‘PCIe AER: can’t find device of ID0000’ during reboot testing, and it requires a reboot to recover. We also find the message ‘pcie_tegra194: module verification failed: signature and/or required key missing - tainting kernel,’ but this message can also be seen on devices that boot normally. What could possibly be causing this issue?

It could be hardware issue if same pcie device can work fine on NV devkit.

Sure, thanks for your reply

Hello, may I ask if the hardware issue you mentioned can be specifically pointed to a particular hardware PCIe channel? Could you also provide the troubleshooting direction?
