Какой адовый привет из прошлого, из моей предыдущей инкарнации здесь.
SML469There is a design defect in the peripheral component interconnect (PCI) to Industry Standard Architecture (ISA) bridge of some chipsets. This bridge is commonly referred to as the south bridge. The jump occurs under a heavy PCI bus load, when the operating system receives a series of unexpected results from the bridge. The operating system detects the unexpected results and computes an amount to add to the performance counter. This causes the returned result from QueryPerformanceCounter to jump forward. See detail in http://support.microsoft.com/default.aspx?scid=kb;en-us;274323.

This change reduced the precision of $ZH and $zu(188) from microsecond to millisecond if we detected the fraud in the machine. The detection occurred during Install/Upgrade Cache, there will be 20 seconds 'calibrating' period.

Ну, т.е. если бы 4.1 поддерживался, то можно было бы заказать SML469 adhoc. Но, боюсь что, в данном случае и железо и билд надо уже выбрасывать.
