Hi all, I'm upgrading some machines from 4.8-RELEASE to 4.10-RELEASE. The machines in question are dual-processor xeon boxes. Now, my boss is adamant in that he doesn't want hyperthreading enabled on the machines. In 4.8-RELEASE things were simple... I just didn't add the "options HTT" line to my kernel config file. In 4.10-RELEASE though, HTT is enabled by default. So, is there any way to shut off the hyperthreading? I've tried disabling it in the BIOS, and had no luck whatsoever. Thanks, DMK PS: A direct reply would be welcome. I'm not subscribed to the mailing list.
