Abstract
A interrupt is generated for all processors in a multiprocessor system when a critical datapath experiences an error. Serialization code in the interrupt handling routine for that interrupt suspends all processors except one and places the suspended processors in a waiting queue while the one processor handles the error. After the error has been handled, the remaining processors are allow to execute the interrupt handler, which simply exits detecting no error.
