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:

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,

I am starting to think my CPU is going bad, but it would
stay bad after a reboot. so ...
Figured out how to reproduce: turn printer on, print something.
Turning the printer back off does not change anything.
Some troubleshooting:
#/$ modprobe -r parport_pc
modprobe: FATAL: Module parport_pc is in use.
# cat /proc/sys/dev/parport/parport0/devices/lp/timeslice
200
Print still prints after the core 2 storm, but
data transfer is 1/10 as fast.
Anyone know how to see who is using parport_pc?
Many thanks,
-T
