So hyperthreading is deliberately disabled by the latest Qubes updates? Is this documented somewhere? > I also have an X1C6 though, with no crazy CPU usage as of today after > updating, rebooting, and suspending/resuming. I don't have CPU usage. CPUs usage idles at < 10%. After resume simply the CPU temperature goes up 10 degrees. It is clearly noticeable as the fans are running more often and faster. This is actually how I noticed the issue. This does not happen without the Qubes update. Also when I do 'xenpm get-cpufreq-para' after update, I get the data for CPU0 and CPU2, but I get errors '[CPU1] failed to get cpufreq parameter', same for CPU3. Before update it showed params for CPU0 to CPU7. So apparently this is not just hyperthreading being disabled. There seem to be troubles with two of the physical cores too. So, if you have an X1C6 with updated Qubes too, do all these things work for you? Which BIOS version are you on? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
