This is in regard to machines running Fully updated F31 and getting
Kernel tainted errors and tpm2-abrmd errors on a recurring basis.

Is this a 5.4 kernel? And does the Computer have Secure Boot enabled?
Could be this:
https://bugzilla.redhat.com/show_bug.cgi?id=1777072#c2

Reported to be fixed in 5.4.7. If you're using that you'll need to be
more specific about what's causing the taint.
sudo journalctl -b | grep -i taint

And tpm stuff is a known bug

I'm not running secure boot. I'm running kernel 5.4.8 since first thing this morning. Here's the grep result:

grep -i taint Taint-TMP-Journal.txt
Jan 10 12:54:38 localhost.localdomain kernel: CPU: 0 PID: 9713 Comm: tpm2-abrmd Not tainted 5.4.8-200.fc31.x86_64 #1

I was getting the kernel tainted error right along with 5.4.7. I've been using that PC today just to see what happens. I just checked and I haven't gotten any more of the kernel tainted errors, but I'm still getting the tpm2 errors. I just checked the screen shots I made of the Details pages in Problem Reporter and it shows I was running 5.4.8-200.fc31_x86-64. The taint error is "E - Unsigned module has been loaded".



	Thanks and Have a Great Day!
