IntelŽ Server Board SE7520AF2 Experiencing Operating System Hang

An operating system hang has been observed under specific configurations of the Intel® Server Board SE7520AF2. The system hang results in a blue screen or freeze of the OS graphical user interface requiring a system reset to recover. Not all SE7520AF2 server boards manifest this anomaly; those that do may take in excess of 2 days to exhibit the hang. The system hang has been observed to occur when the server board is configured with the Intel® Management Module (IMM) and the server board is running Microsoft Windows* 2003 Server operating system in idle mode (i.e. no application running). The event "Processor Internal error (IERR)" is logged in the System Event Log (SEL) and/or may be displayed on the screen during the next boot.

System configurations that do not utilize the IMM and do not utilize Intel® Server Management software (or customer specific server management software) are not susceptible to this issue.
