PCIe errors when booting a Blade 3

Technical Support
#1

I’m getting numerous PCIe errors when booting up a Blade 3 inside a cluster box:

The rockchip rk3588 chip has 5 pcie controllers. Currently, the one in use is pcie@fe150000. Other controllers are not connected to the device. Log-related error reports are normal .
