Changes
The prescribed issue occurs more frequently on idle systems or systems with a very low workload. The low workload pattern causes the CPUs to frequently switch between C-State levels. Each time this occurs, an MCE is generated, thus increasing the number of MCE's and further increasing the chances of the system panicing.
