System or Application Freeze

Freezing is the state where the application has halted the processing of data. A freeze can be at the application or system level. At the application level the freezing is isolated to the process that was running the graphics workload. At the system level, there can be other symptoms in the OS such as a kernel panic, which causes other applications to fail as well. This distinction is important because freezing can indicate the severity of the failure as well as the location. A freeze is usually accompanied by a log dump of the process stack where the exception halted the execution or no indication of the failure at all. Section 2.1.1 is an example of a kernel panic that occurred and caused the system to freeze.
