Most everything is ready, about to launch octobonnie on it for the burn. Octobonnie is an example of an extreme stress test.

Startup is fine, though PCI-e busses and bioses what they are, every now and then PCI-e x8 cards negotiate at x1. A reboot usually solves this. Still looking for the magic setpci invocation that will fix this … we can detect it and report it, but we need the bios writers to do a better job at allowing us to constrain these negotiations. Octobonnie was created by a customer. It positively pounds the crap out of a system. We have caught problems with systems prior to shipping that our other tests did not. Others have taken our original tests in-house as they really do pound on hardware. But we learned from this test, and now use it ourselves. [and there it goes … and we watch the machine] This said, here is some neat stuff about one of these pair:
