Hi All, It looks like my original eMail with embedded picture is going to get bounced, so this one substitutes links to the images. Sorry for the extra work of having to click on the links. My slow down problem is back. And I FINALLY have some good data to show: Here is bpytop. Note that core 2 is swamped at 98%. https://ibb.co/MkNH6vC And here is htop with the same result. Core 2 is at 96%: https://ibb.co/dpYySq6 And as you can tell from bpytop, htop, and the following, no process is showing hardly anything: # ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head PID PPID CMD %MEM %CPU 18455 1 /usr/bin/qemu-system-x86_64 26.2 10.7 18760 16233 /usr/lib64/thunderbird/thun 2.6 2.1 19484 18865 /opt/vivaldi/vivaldi-bin -- 2.0 1.0 18854 16233 /opt/vivaldi/vivaldi-bin -- 1.5 1.4 20101 18865 /opt/vivaldi/vivaldi-bin -- 1.3 0.4 18927 18865 /opt/vivaldi/vivaldi-bin -- 1.1 1.3 19520 18865 /opt/vivaldi/vivaldi-bin -- 1.1 0.5 21841 1 gimp-2.10 /tmp/Screenshot_2 1.0 0.3 14960 1 /usr/libexec/mysqld --based 1.0 0.0 And here are my core temperatures. Core 2 is not abnormal: https://ibb.co/2dccsSS And I can't get Google to cough up how to tell me what is running on a particular core. Both "lynis" and "chkrootkit" (root kit scanners) show me clean. And a reboot ALWAYS clears the issue. When not an issue, I have run fro two solid days without a problem. This time it happened within a half hour. Any words of wisdom? I will hold off rebooting until I have to do my backups tonight. Many thanks, -T I am starting to think my CPU is going bad, but it would stay bad after a reboot. so ... _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
