TPM Error question since 1vyrain mod

[Eugor]

T430 2344-BZU with 1vyrain bios mod, linux mint 20 xfce
Have been running this since Sept with no issues except the "Error Communicating to the TPM" during the boot process. Below is dmesg grep info regarding this.

Code: Select all

agent@X220:~$ dmesg | grep -i tpm
[    0.537747] tpm_tis 00:05: 1.2 TPM (device-id 0x0, rev-id 78)
[    0.585818] tpm tpm0: TPM is disabled/deactivated (0x6)
[    0.673760] ima: Error Communicating to TPM chip
[    0.685758] ima: Error Communicating to TPM chip
[    0.693744] ima: Error Communicating to TPM chip
[    0.701751] ima: Error Communicating to TPM chip
[    0.709754] ima: Error Communicating to TPM chip
[    0.717756] ima: Error Communicating to TPM chip
[    0.725753] ima: Error Communicating to TPM chip
[    0.733749] ima: Error Communicating to TPM chip
agent@X220:~$ 

I use this as a personal laptop and not part of any it network or structure.

Should I be concerned about this error and TPM disabled/deactivated ?

Like I said, I have experienced no problems, but am still ignorant as to the scope of how TPM works and impacts the system. I know there were posts in 1vyrain sticky regarding windows and the fingerprint reader. I do not use the fingerprint reader on mine.
Thanks for any insight.
Was not sure if I should post here or in 1vyrain sticky

In your usage scenario you shouldn’t worry about TPM. And obviously, TPM will report errors after tempering with your system hardware, it’s part of it’s design.

There is an ebook available on what exactly this piece of hardware does link

You can go to the Bios is turn off TPM. I always turn it off to stop these messages
