You can solve the problem by going into the bios setup and disabling HT.
Or you can suffer the performance loss. Your choice.

Hi all, I have a Server box running OpenBSD 3.6, Intel 3.0 HT
processor, I've compiled a kernel with SMP support, but where can I
verify if it's really using SMP? Under GNU/Linux distros i run cat
/proc/cpuinfo and it shows me two processors. Under OpenBSD I've
mounted the kernel filesystem and I toke a look at ncpu but it still
saying that there is only one processor. Can anyone tell me what's
going wrong? And how can I solve it?
For now, thanks.
Is there absolutely no benefit to HTT at all?
Systems we run HTT with (Unix) seem to perform slightly better and
building world has been noticeably faster.
No matter what I set the BIOS to - I cannot get SMP/HTT to work in
OpenBSD, but it does work with others
I have the same exact proc, P4 3gghz HT. I never got it to work with HT
so I leave it disabled and run it as though no HT. Here is my dmesg when
I enable HT and run Generic.MP:
