Thank you, that's quite a useful bit of info there! Do you ever see a timeout message with 5.15.75 (if so, logs please?).

Thanks. It's a head scratcher.. You aren't seeing the dev_err message being printed at all, so I don't see how my patch can impact you.

Odd. The dmesg you posted at first doesn't even seem to be hitting my patch.

Where have you attached it? 😃

Do you see a message with "PCIe link training gen1 timeout" when you attempt to boot up with the kernel that was failing to boot earlier?

Would one of you be able to help me troubleshoot with a serial console on your Rock Pi 4B?

Nice, glad I seemed to have fixed it for you! Could you post dmesg as well? I want to see how many times training failed.

The pcie_rockchip_host driver is buggy. Give latest a go, should work after https://github.com/armbian/build/pull/4308.

@elyograg: New builds should work after https://github.com/armbian/build/pull/4308. Let me know if this works for you or not.

I've fixed this here: https://github.com/armbian/build/pull/4308

I'm running into the same issue and solution (`modprobe -r pcie_rockchip_host && modprobe pcie_rockchip_host`) on a NanoPi R4SE. It's breaking my LAN port. =/ Related:
