Symptoms
  • Intel X520-2 NICs (8086:10fb, 8086:0003) are not recognized by Gaia OS in 64-bit mode - output of Expert command 'ifconfig -a' or Clish command 'show interfaces' does not show these interfaces.

  • The following error is seen in dmesg:
    ixgbe: XXXX:XX:XX.X: ixgbe_probe: HW Init failed: -15

Cause
  • The PCI bridge memory mapping is truncated to 32-bit.
  • If the PCI bridge and the PCI device behind it try to use 64-bit address range, the device will fail to load.
