Len,
I don't think that the CPU model has much to do with anything, it is pretty much chipset related. My last remark about buying you a mobo for debugging purposes was a vain attempt at humor.
I'm just surprised of the lack of support the vendors and NVIDIA/AMD are giving. I realise that Linux may be only a marginal part of the market for those companies so it is not commercially justifiable to invest a lot of time in this.
We all appreciate whatever input you may have, because a solution without indepth knowledge of how ACPI/APIC code handles stuff is probably needed to tackle this issue.
All I can do is gather info, and I'm currently thinking of a plan to get the info we need.
Regards,
Arjen
