I'll look into the build issue but I'll worry more about fixing all builds when all the remaining bugs are shaken out - it won't cause any demonstrable detriment to enable SMT as a workaround for now. There's no difference in terms of what governor you should choose on muqss. Glad to hear you're benefiting from the interactivity too.ckhttps://www.blogger.com/profile/02904761195451530213noreply@blogger.comtag:blogger.com,1999:blog-6469704299235308349.post-44532764748909751672016-10-11T04:22:29.646+11:002016-10-11T04:22:29.646+11:00https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
