[SOLVED] A TPM Error Occured to read a pcr value And Random

Hello everyone,

I have some booting errors about TPM, and here they are:

$ dmesg | grep tpm
[    1.870415] tpm_tis 00:05: 1.2 TPM (device-id 0x0, rev-id 78)
[    1.916368] tpm tpm0: A TPM error (6) occurred attempting to read a pcr value
[    1.916387] tpm tpm0: TPM is disabled/deactivated (0x6)
[    1.933399] tpm tpm0: A TPM error (6) occurred attempting get random

I followed this quesiton and according to uname -r, which outputs:

4.16.7-1-ARCH

I have a kernel more modern than what fixed that question.

The people who answered the question that I linked wanted the full output of dmesg, so here it is:

Any Help Will Be Appreciated.

Hello SealsRock,

As you can saw in my previous post, it's a kernel issue.
4.16.7-1 is still in testing. Maybe waiting for the stable release will fix that. That's been said, I don't like "waiting for a pcr value". I will read the kernel commit before upgrading...

I Hope...

4.16.7-1 is still in testing. Maybe waiting for the stable release will fix that.

If something is changed then it would require a new release that would need to also pass through testing.
@SealsRock12 what kernel version did this error first occur with?

@loqs When I had Manjaro Linux on 1.14, this occurred also. I will install linux-lts and see if booting to that kernel works.

@loqs Thanks, you helped solve the random and the pcr value.

Marking as solved.
