Comment 7 for bug 129172

When you say "looks like a hardware problem", I'm not quite sure what you mean. At first, I'd be inclined to agree with you, however it's entirely new hardware, it passes memtest fine (for 12 hours), and everything works perfectly, with the exception that I can't use all the physical RAM. All the diagnostics seem to be OK.

I guess we could think of this as a (design) flaw in the motherboard/chipset, which prevents it from working properly with the current Linux kernel - but I don't think that gets us very far ;-) Do you have any suggestions for further tests which could narrow this down a bit? Thanks for your help.
