TPM interrupt not working, polling inst

lc flag

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 :-)

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
