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.
