[WOLK-devel] xeon hyper-threading/smp problem

[Mike B. <Mik...@fu...>]

Hello,
I've got here a single processor Intel(R) Xeon(TM) CPU 2.00GHz
(looks like 2 processors to os):
redhat smp kernel detects 2 processors, works fine,
other smp kernel's i've tried have also detected 2 and worked,
but wolk detects only 1:

Processors: 1
Error: only one processor found.
WARNING: No sibling found for CPU 0.

With some PaX features enabled it won't even boot, so I turned those off =
and at least now it boots but still only sees 1cpu.
Same smp wolk kernel even w/PaX options enabled boots and works fine on =
a dual pIII machine.
Any help/suggestions would be great
thanks,


config for smp wolk: (tried w/4.0s and 4.1s)
