[SOLVED] Kernel [Firmware Bug?] tpm_crb MSFT0101:00: [Firmware Bug]

(I have already solved this. Idk how to close this question.)
I decided to check out the log by using ''journalctl -p 3 -b'. I noticed there is an error i got when booting:
tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0xfed40000-0xfed4087]
A few questions: Is this normal? If not how would I fix this?
I don't know too much about this error. If somebody could explain what could be going on it might help

Nevermind, you actually just had to turn off TPM to fix it.

Most ACPI implementations are off-spec. Unless there's an actual problem, you can ignore them.
Turning off the TPM prevents the tpm driver from loading and so it won't run into that error. The "fix" is simply that what is not there also cannot be broken.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
