Subject: smp: am i seeing double?
A quick question about hardware. I'm 99% sure my box has 2 Xeon processors in
it. I had installed the sarge kernel then got the
package and installed smoothly using `dpkg -i <kernel-image... .deb>`,
rebooted into that kernel. I now seem to be seeing 4 (four!) processors eg as
reported by `top`, `cat /proc/cpulist` and in the /var/log/messages file.
(Aside: with the uni-processor kernel, `top` only reported 1Gb memory but the
smp kernel, correctly, reports the 2Gb memory
I've just rebooted to WinXP and the SystemProperties implies there's 2
processors on the 'General' tab, but lists 4 on the
Hardware->DeviceManager->Processors tab and indeed the TaskManager also
implies there's 4 CPUs.
Any ideas what's going on?
