Intermittently ereport.io.device.inval_state is seen after SP force failover (26778934)

On SPARC M8 servers, the USB host controller that connects SPs to the system might hang on device disconnect (for example, during SP failover). During the recovery process, while the USB host controller is not operating correctly, an FMA ereport (device inval_state) might be generated.

Recovery: You can safely ignore FMA ereports that are generated in this case.

Workaround: Issue the fmadm command to repair the faulted component.
