The pci-probe-policy variable should only be used on Oracle SuperCluster engineered systems to specify how probing for PCIe devices is conducted. For all non-SuperCluster systems, the value of this property should not be changed. If you've changed the value of this variable, you might witness unknown system behavior.
Workaround: No workaround is available for this error. Do not change the pci-probe-policy variable on non-SuperCluster systems.
