    摘要： Illustrative embodiments manage deadlock in a data processing system during an IPL process that includes monitoring the usage of locks in the Hardware Object Model (HOM) of the data processing system. The process further includes detecting a deadlock condition in response to an indication of the IPL process in the data processing system entering a hung state when at least one lock is in use. The process also includes handling the deadlock condition by performing one or more of the following: recording error information for the deadlock condition, and terminating the IPL process.
