    Hyper Threading - wont enable

    Hey,

    I have a brand spanking new install of 8.04 on a P4 2.8 box.

    For some reason HT wont turn on. The result of uname -a is:

    Code:
    2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux
    and I've edited this line to read:
    Code:
    kernel          /boot/vmlinuz-2.6.24-16-generic root=UUID=7b41f149-b250-48bd-8a86-7c752963de4d ro quiet splash ht=on

    But I'm not seeing two CPUs in the System Monitor, so I'm guessing HT isnt on?

    any help is much appreciated

    What do you get as the output of
    Code:
    cat /proc/cpuinfo
    or
    Code:
    cat /proc/cpuinfo  | grep processor
    for a more concise output.
