ABSTRACT:
A method for managing multiple hot plug operations in an information handling system is provided. An instruction for initiating a new hot plug operation is received, the new hot plug operation including one or more hot plug system management interrupts (SMIs). Another hot plug operation currently ongoing at the time of receiving the instruction for initiating the first hot plug operation is identified, the ongoing hot plug operation also including one or more hot plug SMIs. In response to identifying the ongoing hot plug operation, the initiation of the new hot plug operation is restricted such that the ongoing hot plug operation may be completed. For example, hot plug SMIs not related to the ongoing hot plug operation may be disabled until the ongoing hot plug operation is completed. As another example, the new hot plug operation may be queued and performed upon the completion of the ongoing hot plug operation.
