Bl460c G6, conrep, linux - can't disable hyperthreading
I try to disable hyperthreading with conrep on a Bl460cG6 with Bios I24 07/25/2009. I use conrep version 2.20c on RHEL5. This does not work, albeit conrep seems to change the setting it's not active after the next reboot. Changes work for other settings like ASR timeout. I noticed that rbsu> does a "power cycle" when I change hyperthreading settings, do I need to do something special to make the changes permanent beside a simple reboot ?

I have the same problem. When enabling or disabling the config the change appears whenever I do a conrep -s.
But when performing a reboot or poweroff/poweron it doesn't change the amount of cpu's

Re: Bl460c G6, conrep, linux - can't disable hyperthreading
I noticed the same issue. Run conrep, reboot, HT is still enabled (I've actually had it enable itself on systems where it previously disabled), reboot again and then it's disabled. I haven't tried a third reboot to see if it comes back.
