From: Michael Pobega <mpobega@xxxxxxxxxxxxx> The Dell Latitude 3350's ethernet card attempts to use a reserved IRQ (18), resulting in ACPI being unable to enable the ethernet. Adding it to acpi_rev_dmi_table[] helps to work around this problem. Signed-off-by: Michael Pobega <mpobega@xxxxxxxxxxxxx> [ rjw: Changelog ] Signed-off-by: Rafael J.
