I agree. I've booted on 16 way machines and been annoyed by the kernel
messages. Did you set the dmesg buffer size to 128k or did you capture
the boot messages with a serial card?
The arch/ia64 code is not the only offender; ACPI is terribly verbose too.
I'm going to cc the acpi list too. See comments below.

The information here, such as it is seems to be a duplicate of the SRAT
information above.

There's a number of things here that annoy me. One is the stupid
"Processor 8192/1 is spinning up". I would expect "Processor 2/96
is spinning up", but why have this line at all? I'd also like to see
"Bringing up 3", "Processor 1 has spun up..." and "CPU 1 IS NOW UP!" go
away. That'd cut us down to:

A 40% reduction in per-cpu verbosity ;-)
