This is true. But the means of actual hardwiring of the APIC to the
board can apparently be accomplished in more than one way, which might
be relevant to the means of fixing or supporting the APIC. So Intel
might be able to privide the info in place of SuperMicro, but I don't
think they are all that interested either, and even if they are, there
is the issue of the actual connection of the APIC to the board.

I hope stability has gone up, it would be a cheery note. What I worry
about though, is that if we don't know *why* it is now working, there
might not be any consistent means of reproducing stability for the
chipset in future kernels. If the actual fix is understood, I'd have
faith that stability would continue far into the future. Right now I'm
hoping that the upcoming ServerWorks WS chipset will work as a
replacement (apparently nobody will be manufacturing boards on this
chipset until roughly December). That chipset has the 64 bit pci support
for ultra 3 scsi and gigabit network cards, along with the agp 4x
support (useful for those of us looking forward to OpenGL and the newer
generation of video cards).
Via is apparently coming out with an SMP chipset that has agp 4x, but I
don't think it supports 64 bit pci.
