An uncorrectable error is detected in the data of a computer system. The erroneous data is allowed to be stored in first and second caches of the computer system while the system runs first and second processes, the first process being associated with the data. The first process is terminated when an attempt is made to load the data from the cache. Meanwhile, the second process continues to run.

Method and apparatus for handling data errors in a computer system

A method and apparatus for handling cache snoop errors. According to one method disclosed, a snoop cycle having a snoop address is generated by a first bus agent. A second bus agent detects a snoop error in response to that bus cycle. As a result of the detected snoop error, the snoop error is signaled to the first bus agent, the bus agent which generated the snoop cycle.
