Your Microsoft Windows Server 2003-based multiprocessor computer with an AMD chipset may occasionally stop responding (hang).


This problem may occur if your multiprocessor computer has an AMD-8131 HyperTransport PCI-X Tunnel Data chipset installed.

Specifically, this problem occurs when multiple nonmaskable interrupts (NMIs) occur at the same time. An NMI is an interrupt that cannot be overruled by another service request. A hardware interrupt is defined as nonmaskable if it bypasses and takes priority over interrupt requests that are generated by software, by the keyboard, or by other installed devices.
