Flooding Console With PCIe Bus Errors

Support
1

NethServer Version: 7.7.1908

When a display monitor is connected (DVI), the console is flooded (~2 seconds) with:

PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=000a(Transmitter ID)

device [1022:1483] error status/mask=00001100/00006000
[ 8] RELAY_NUM Rollover
[12] Replay Timer Timeout`

It appears as the sever is operating normally, however with the exception that I cannot log onto the console (not the web interface). The terminal in the web interface operates properly (no PCIe messages).

Do I need to be concerned about this? How can I correct this so I can interact with the console if needs be?

TIA

Some Internet search points to a problem with power management and a workaround by adding pcie_aspm=off boot parameter.

Good catch, thanks for that,

Putting the option into the Grub entry worked but I could not find a way to make it persistent. I toyed with using grub-mkconfig to re-generate grub.cfg but I am not sure this system is booting UEFI.
