   nvme 0000:02:00.0:    [ 0] RxErr                  (First)
+=== Option 1 ===
+This worked to remove the error and gave the lowest power usage (4 Watt).
+Add extra kernel boot parameter: pcie_aspm=off, acpi_mask_gpe=0x6d into /etc/default/grub.
+  * pcie_aspm=off : Let BIOS manage ASPM for pcie bus avoiding "pcieport 0000:00:1d.0: AER: Correctable error message"
+  * acpi_mask_gpe=0x6d  :  Suppress "ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_L6D]"
+  # nano /etc/default/grub
+  GRUB_CMDLINE_LINUX_DEFAULT='quiet pcie_aspm=off acpi_mask_gpe=0x6d resume=UUID=40794123-1105-4c1
+  # update-grub
+=== Option 2 ===
+This also worked to remove the error, but gave a slightly higher power usage (7 Watt) than Option 1.
 Solved by disabling ASPM on bridge and/or drive:

   # Disabling ASPM on nvme drive
   /usr/bin/setpci -s 02:00.0 0x90.B=0x40
+This can be achieved by creating a specific systemctl service (aspm-overrule.service).
