An apparatus and method for dynamic suppression of spurious interrupts in a computer system. More specifically, there is provided a method that comprises providing a look-up table comprising source IDs and corresponding time delays for each of a plurality of interrupt lines, monitoring each of the plurality of interrupt lines, and updating the time delays in the look-up table based on the monitoring of the interrupt lines, and a system for implementing the method.

Method and apparatus for dynamic suppression of spurious interrupts

The disclosed embodiments provide an efficient method and apparatus for avoiding hangs when a computer system is unable to complete a proper boot. Booting is attempted from each device in a standard boot order list until a successful boot occurs. If the standard boot order list is exhausted without a successful boot, the boot sequence is retried after a predetermined time period.

Autonomous boot failure detection and recovery

A hot pluggable bus in a computer system includes one or more slots for receiving hot pluggable bus adapters and a hot plug controller also coupled to the bus. When a mechanical member associated with a slot is actuated by the user, a signal is sent to the hot plug controller to indicate that the user is about to remove the bus adapter. At that time, the hot plug controller programs a control register to enable a system error signal to thereafter permit the hot plug controller to assert the system error signal when it detects a master abort pertaining to an attempted transaction to the slot which is vacated by the user removing the bus adapter from the slot.
