I didn't write Virtual Machine at all - all of them are bare metal with
monitor (PC).

Here's another similar report:

"using the infineon kernel module"

It seems this 'infineon' TPM have a problem.

If you can fix this on linux side, by not spamming journal, that'll be
appreciated by everyone who have similar symptom.

I _could_ disable TPM via BIOS, but I'm not sure I can do this because:
1. This PC's BIOS is old & it may not have TPM settings
2. I had an incident when I disabled TPM & could not boot anymore when I
was using Windows. Now I moved everything to Debian, I don't want to
touch TPM at all as it may break my Encrypted KVM...
