SubjectRe: IO-APIC on nforce2 [PATCH] + [PATCH] for nmi_debug=1 + [PATCH] for idle=C1halt, 2.6.5
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
