Bug#670797: linux-image-3.2.0-2-686-pae: CPU load not being distributed
Never, I haven't. Actually, I did knew it was possible to set the affinity, but I was never curious about it until I got this. and checked the cpu_smp_affinity and was always set to 'f'
I did, however, installed some time ago 'ulatencyd' and 'schedtool', but I uninstalled them (--purge remove) before creating the bug (and yes, the system was rebooted after remove the packages).
Would it be possible that those packages screwed something else? After changing all my processes affinity, I haven't rebooted the system, so I don't know if I'm going to get this again or not. Will check again tomorrow.

I don't know. Did you explicitly configure the affinity of anything

Design a system any fool can use, and only a fool will want to use it.
