Failure to Disengage CPUs

In some instances, the CPU power control cannot disengage the affected CPU(s) from the Solaris software environment. For example, if the high temperature condition occurs when only one CPU/memory board with two processors is in the system, processor one will not go offline due to its being the last processor in the system.
