TPM interrupt not working, polling inst

Question

after I installed Ubuntu 22.04.2 and rolled out the MOK this message appears on every boot.

How can I fix this?

$ sudo mokutil --sb-state
SecureBoot enabled
$ sudo dmesg | grep -i tpm

I have the same issue, Kubuntu 22.04.2. LTS Dell Precision 7550 latest BIOS (April 2023)...

I've tried various settings in TPM appart from disabling it, becuse I think the function is important :-)

Also tried to disable secure boot but as stated on other thread it shouldn't have anything with this error to do...

Hope there is some guru out there that can help a simple user :-)
