This is a hardware counterpart of Not My Version pattern. Some problems manifest themselves on different hardware not used at the time of the product testing. In such cases we can look at kernel and complete memory dumps, extract hardware information using !sysinfo command and compare differences. This is similar to Virtualized System pattern and might provide troubleshooting hints. One example, I have seen in the past, involved a graphics intensive application that relied heavily upon hardware acceleration features. It was tested with certain processors and chipsets but after a few years failed to work on one computer despite the same OS image and drivers. !sysinfo command revealed significant hardware differences: the failing client computer was newer faster multiprocessor machine.
