I confirm the reported TPM error message "A TPM error (6) occurred after attempting to read a pcr value", which recently started to appear during boot on my ThinkPad T420s running Ubuntu 14.04.3 LTS, currently with kernel 3.19.0-30.

I followed RikT's comment at https://bbs.archlinux.org/viewtopic.php?pid=1086005#p1086005 to disable the security chip in the BIOS (which is different from the default setting "inactive"), since I am not using it anyway. Now I only get

$ dmesg | grep TPM
[ 0.540023] ima: No TPM chip found, activating TPM-bypass!

which does not show up during boot (no error). My BIOS version is 8CET51WW (1.31) released at 11/29/2011.
