After upgrading to Ubuntu 22.04 lts on my hp desktop and getting 5 or 6 repeated "ima: error communicating to tpm chip" messages quickly upon boot, in bios I eventually changed "Embedded Security Device" to "device hidden" and get "Can't evaluate _CRS 12311" quickly during boot. So, I decided to just learn to live with it, as nothing seems to be affected. See thread concerning this at: https://www.linuxquestions.org/quest...on-4175711629/

So, today, I went ahead and upgraded my HP Pavilion notebook to 22.04 lts also. I get a barrage of messages, including some related to tpm again. So, in BIOS, I hid/disabled the tpm. Now I get bios & firmware messages upon boot, but just a few lines of it.

Concerning the notebook. Neither having tpm enabled/shown or hiding it/disabling it seem to have any adverse effects on the operating system. I do wander though, which is the less of the two evils (having the tpm on or off). See 2 attached photos of the screen when it's on and off. Comments and opinions please....

I have problems attaching files. The pic in the first mssg is after tpm is disabled/hidden.

Here are the "barrage" of messages I get before doing that:

Comments please. Would just like to know which "state" users here would think it's best to leave the bios in - either tpm hidden/disabled or enabled.

Thanks so much in advance!

I have about a dozen PCs with those modules. On none do I have, or have I ever purposely had, one enabled. I can't recall any new messages on any I've upgraded to 22.04 on, but none are on HPs either.

Possibility 1:
Your BIOS is an old version and latest version will fix this problem.

Possibility 2:
TMP chip or something other "between CPU and TMP" is broken.
If TPM chip is plugged in and not soldered try to unplug and plug it.

Since you 'wander' about this, you may want to read/understand the user manual and actually update the BIOS, as you were told before. Again, your TPM module needs an update. And you were also told in your other thread that it won't hurt anything either way.

Don't see much point in opening more threads for essentially the same thing, especially if you're not going to bother to listen.
