Resolved via IRC: 08:39 < Ramereth> mjw: hmm, hyperthreading is enabled. I wonder if the kernel cpu mitigations that are enabled by default in the kernel are turning it off. Do you want me to adjust the kernel parameters to not do that? 08:40 < mjw> Ramereth, if you could and know how then yes please, since the same user (builder) runs everything there really isn't any data leak to prevent. 08:41 < Ramereth> ok, give me a moment to do that 08:41 < mjw> Or if there is, there are much simpler ways to leak things than trying to extract data through subtle timing issues exposed by hyperthreading :) 08:46 < Ramereth> CPU(s): 16 08:46 < Ramereth> mjw: looks better 08:47 < mjw> Cool!\ 08:47 < Ramereth> FWIW I just updated the ignition file in case we end up rebuilding it later to make sure that's the case again FWIW I adjusted this on the running system by doing the following: rpm-ostree kargs --replace=mitigations=auto,nosmt=off And then rebooted the system. Is there anything else you need for this? -- Lance Albertson Director Oregon State University | Open Source Lab
