Ah... did NOT have ACPI enabled. Did not know it had to be, for SMP to
work!
I enabled it, compiled the kernel, and /proc/cpuinfo sees 2 CPUs, but top
doesn't.
After spending ages trying to figure it out, I found the version of top
that comes with Debian 3.0 does NOT have SMP support.
So I downloaded the backported version from:
http://people.debian.org/~nobse/debian/woody/backported/procps/
and after top launches, press 1 (or set the appropriate cmd line
parameter) and it works great.
I did ACPI a little different than you though... I have:
> # CONFIG_ACPI_HT_ONLY is not set
set as y/1 (and therefore everything else set as n/0), as I don't need all
the "acpi_power" and other stuff, just want SMP to work.
So it's working now. Thanks for your help!
