Driver seems to conflict with RPI cm4 onboard wifi about realtek-r8125-dkms HOT 2 CLOSED

Thanks for the suggestions. I have another system so I will try it with that and see if I get the same issue. I can put a fresh install of Linux/Raspbian on that and see what happens.

Hi.

Unfortunately, I have no clue either. And I don't have Raspberry Pi 4 CM. 😅
But I think there's a question we have to know clearly to narrow down the root cause: Is it a hardware issue or a software issue?

I suggest,
If it is in hardware, seems another PCIe device should occur the same error too. Then the root cause must be kind of a circuit problem.
If it is in software, then seems you should try another Linux distro for Raspberry Pi 4. And I think that should have a 5.10 kernel at least because the modern Linux kernel has the firmware binary for r8125 2.5GbE ethernet card. So that we can filter out one suspicious thing from the potential culprits.

Hope this helps.
