tpm error

[Michael Heuberger]

I see this in the dmesg

[ 0.649779] tpm_tis 00:05: 1.2 TPM (device-id 0x0, rev-id 78)
[ 0.695984] tpm_tis 00:05: TPM is disabled/deactivated (0x6)
[ 0.751948] tpm_tis 00:05: A TPM error (6) occurred attempting to read a pcr value

What should I do?

Having the X1 Carbon Thinkpad Laptop here on Ubuntu 14.10 ...

Thanks for any clues

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.0 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Michael Heuberger (michael.heuberger)]

I cannot answer any of these questions and am unable to test with the latest upstream kernel.

[penalvch (penalvch)]

Michael Heuberger, as per http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1-carbon-type-20a7-20a8 an update to your computer's buggy and outdated BIOS is available (1.20). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed.

Thank you for your understanding.

[Michael Heuberger (michael.heuberger)]

Thanks for that Christopher. Unfortunately the Lenovo link does not provide any BIOS updates for Linux, so looks like I am unable to update BIOS on a Linux machine.

And here is the output to the above command:
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
GRET40WW (1.17 )
09/02/2014

Let me know how to proceed.

[jkbkot (jkbkot)]

I've noticed the same message in my dmesg output. I've already upgraded my BIOS to the latest one for T420:

$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
83ET76WW (1.46 )
07/05/2013

@michael.heuberger: I've downloaded the BIOS Update Bootable CD: http://support.lenovo.com/us/en/downloads/migr-77076#make and used geteltorito to convert the image and dd to write it to USB. You can follow the guide here: http://www.lenzg.net/archives/358-Updating-the-BIOS-on-my-ThinkPad-T440-without-Windows-or-a-DVD-Drive.html

[jkbkot (jkbkot)]

I've tested the latest v4.0 kernel and the problem persists.

[Michael Heuberger (michael.heuberger)]

@jkbkot thanks for the link - will give a try

@penalvch, why status incomplete? jkbkot just confirmed, the bug still exists, even on the latest version ...

[Dennis (deki24)]

Installed latest upstream kernel 4.0.0-040000.201504121935. Same problem there.

BIOS: G6ETB0WW (2.70 ) 02/05/2015

[penalvch (penalvch)]

Dennis, it will help immensely if you filed a new report via a terminal:

Please feel free to subscribe me to it.

[Dennis (deki24)]

Alright new bug entered #1449079

[jkbkot (jkbkot)]

Still the same problem with 4.1.0-040100rc1-generic #201504270235

[Sebastian Meyer (wastl)]

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.
