Subject: [gentoo-dev] SMP kernel halts system - hyperthreading??

Dear gentoo-dev,
If some of you recall, I wrote to the list about a system halt resulting
from running C++ codes and it possibly having to do with nVidia graphics
or XFree 4.2.1.
Well, the problem persists in text mode also. It happens when 3 or more
CPU-intensive processes run simultaneously on the machine. I have an SMP
kernel (2.4.19-gentoo-r7) with 2 Intel Xeon 2.2-GHz processors equipped
with hyperthreading technology.
I have 4 processors initialized at boot time, and 4 processors show up in
"top". This is probably because of hyperthreading, as otherwise there
should be only two.
How do I turn off hyperthreading? Do you think hyperthreading is what's
breaking my system and it could be more stable without hyperthreading?
Can a certain process be confined only to a certain processor?
Thanks for any help!
Denis
