Why does FreeBSD 8.-0 think that my Dell SX260 have "non-unform processors"?
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:

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?

Same in your 7.2-STABLE dmesg. Something set that way in BIOS?

Only spotted a verbose dmesg for 7.2-STABLE there, not for 8.0? > 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. I suppose you have HTT disabled in BIOS? > What excatly is non-unform here? I don't know, but suspect the detected half CPU speed may be a clue? > References: > 1) http://sites.google.com/site/tingox/sx260 > 2) http://sites.google.com/site/tingox/sx260_freebsd > -- > Regards, > Torfinn Ingolfsen cheers, Ian

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?
