That suggests you may have rebuilt your kernel without SMP support. > how can i verify that HT is working? my mobo (IBM 8189) doesnt seem to have an on/off for HT, so my first inclenation is assume that its on (we have many windows machines running on this hardware, and HT never seems to be a problem with those). > > any pointers would be appreciated (and yes, already know alllll about the security advisories... :) And about the possible poor performance I assume :) Kris
