A tpm error (7) occurred attempting to read a pcr value
I've been annoyed with this error for a while now.
I've tried adding blacklist tpm_tis to the etc/modprobe.d/blacklist.conf
I've tried FSCK'ing
I've tried looking at the block ids to make sure there's not some weird duplicate.
And I've disabled TPM in the BIOS.
But this error is just like a clingy ex who just won't go away. My functionality isn't affected. It boots, logs in, does what it needs to do. I just can't get rid of this.
It seems that error code 7 indicates that TMP is disabled. I also found this, which seems to indicate it's an old kernel bug.
