-====== Dell Optiplex 3070 ======
-----
-===== ASPM errors BIOS =====
-Power saving errors in journalctl:
-  pcieport 0000:00:1d.0: AER: Correctable error message received from 0000:02:00.0
-  nvme 0000:02:00.0: PCIe Bus Error: severity=Correctable, type=Physical Layer, (Receiver ID)
-  nvme 0000:02:00.0:   device [1344:5410] error status/mask=00000001/00002000
-  nvme 0000:02:00.0:    [ 0] RxErr                  (First)
-Solved by disabling ASPM on bridge and/or drive:
-  # Disabling ASPM on bridge
-  /usr/bin/setpci -s 00:1d.0 0x50.B=0x40
-  # Disabling ASPM on nvme drive
-  /usr/bin/setpci -s 02:00.0 0x90.B=0x40
-===== ACPI errors BIOS =====
-Getting rid of ACPI error:
-<code>
-# kernel: ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_L6D] (20240827/evgpe-511)
-# kernel: ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GLAN.GPEH], AE_NOT_FOUND (20240827/psargs-332)
-# kernel: ACPI Error: Aborting method \_GPE._L6D due to previous error (AE_NOT_FOUND) (20240827/psparse-529)
-</code>
-==== Option 1 ====
-Create service with:
-  /usr/bin/echo "disable" > /sys/firmware/acpi/interrupts/gpe6D
-This works but +/-30 seconds after boot this entry is being overwritten again to "enabled".
-It is not clear what is doing this
-==== Option 2 ====
-Adding the 'acpi=off' option to grub did not suppress these errors.
-But adding 'acpi_mask_gpe=0x6d' seems to work.
-  # nano /etc/default/grub
-    GRUB_CMDLINE_LINUX_DEFAULT='quiet acpi_mask_gpe=0x6d'
-  # update-grub
