My suggestion as a workaround, would be, in the event, you see errors in system event log like :
57 hpqilo2 Duplicate thermal sensor instances: 5
57 hpqilo2 Duplicate thermal sensor indices: 6
To try installing iLO2 Driver 1.11.0.0
If after installation of driver and possible OS restart errors persist, try versions 1.0.8.0 and 1.0.9.0 respectively.
