It transpires that this refers to PCI Espresso Bongo stability and that there are some problems with certain Intel 915 boards and with ATI and Nvidia cards.
There is a big hassle and "argy bargy" going on about this between Intel, ATI and Nvidia, as the discrete graphics card manufacturers believe Intel is far from being ready with its 915 chipset.
As for 925 boards they are not affected by this problem. As we have a few 915 boards and a handful of PCI Espresso Bongo cards, we will try to confirm these claims.
Our "problem" is that we always get the best of the rest cherry picked samples that can be spared.
We also heard that Intel chipsets will be revamped quietly. We don't know which cards and boards are affected at this time. Still, introducing new tech like PCI Express is often a case of roses, roses then thorns thorns. The graphics card manufacturers are, quietly, livid. ยต
