Package: linux-image-amd64
Version: 6.12.90-2

I freshly installed Debian Stable on some PCs and those are getting
spammed by the kernel. Those are way frequent, pushing other logs in
journal.

Could you please tone this down, maybe stop writing to journal so
frequently?

This is not just my problem, because searching for it yields similar
reports;

(I thought about blacklisting the 'tpm_infineon' using modprobe but I'm
not sure this is the good solution so I'm not doing it. I'm running
Debian using "Encrypted KVM" so if I disable tpm I might lose access)
