SMP Hyperthreading


Hi

Can anyone point me in the right direction on how to get Hyperthreading working. I am using Openna Linux which seems to have detected Hyperthreading and installed the SMP Kernel.

[root@rw1 log]# uname -a
Linux XXXXX 2.4.22-1 #1 SMP Sat Oct 18 05:53:05 EDT 2003 i686 unknown unknown GNU/Linux

When I look at /proc/cpuinfo I see 1 processor

[root@rw1 log]# cat /proc/cpuinfo

This is my dmesg log
