ACPI region does not cover the entire command

do you think this is something I can safely ignore?

Code: Select all
dmesg
.......
[    5.428167] tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0xfed40000-0xfed4087f flags 0x200] vs fed40080 f80
[    5.428243] tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0xfed40000-0xfed4087f flags 0x200] vs fed40080 f80
.........


apparently I have no major issues but I'm wondering what it is eventually missing?
might be something related to the update of the bios?

is it eventually worth thinking to fix it somehow, even if the system is working fine (at least it seems to me)
Code: Select all
uname -a
Linux max-debian 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux


what do you think about it? any suggestion?

thanks

And what did your internet searches tell you about that error message?

ok, I managed to find something clear here
https://forum.manjaro.org/t/firmware-bu ... 1-00/52124

the problem it's about TPM trusted platform modules and the eventual blacklisting of that modules

now the problem is I can not find an entry of TPM in the bios even if some of that misterious modules are present in my sysstem

Code: Select all
lsmod | grep tpm
tpm_crb                16384  0
tpm_tis                16384  0
tpm_tis_core           20480  1 tpm_tis
tpm                    65536  3 tpm_tis,tpm_crb,tpm_tis_core
rng_core               16384  1 tpm



still remain the question: should I stay or shoud I go?

it's not clear to me what to do because I'm a bit scared of messing up everything considering that I can't spot any serious problem so far, apparently...
