Hi, I just booted my Dell OptiPlex SX260[1] from a usb memory stick with FreeBSD 8.0-release on it. Part of the dmesg output is: Copyright (c) 1992-2009 The FreeBSD Project.

Why does FreeBSD think that this machine has "non-unform processors? Ok, the Pentium 4 in it can proably do hyperthreading, but that isn't much to talk about. What excatly is non-unform here?

Can you please reboot and show a verbose dmesg from this system? Also, how many CPUs does this system actually have? It appears that in the 7.2 dmesg at 2) above, two are detected but only one is ever used - are you explicitly disabling hyperthreading somehow?
