Hi All,

It looks like my original eMail with embedded picture
is going to get bounced, so this one substitutes links

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 ...


It is going at it again today (core 2 swamped with
interrupts from my parallel port card).  I just tried
to print four pages.   They printed, but it took 10 times
as long.  Chuckle.

I have a new card on the way
