Linux has stopped booting because of TPM 378 error

[JSale7]

With Ubuntu 18.04 (installed and/or usb boot), 18.10 (usb), 19.04 (usb) and linuxmint-19.2-cinnamon (usb), I cannot boot my NUC.

Initially, the (Ubuntu 18.04) box started fine, but after a couple of months, occasionally the box would simply stop. Shortly thereafter the linux versions mentioned above will now not even start.

So, under no circumstances, can I start the box and get to a console (except for Advanced Ubuntu startup options ... which leads back here anyway ... the startup just dies).

Here is the log as far as I can capture it visually before we are dead:

tpm tpm0: A TPM error (378) occurred get tcp per allocation Couldn't get size: 0x000000000000000 /dev/nvmem2s1g2 recovering journal /dev/nvmem2s1g2 clean .... files, .... blocks

And my configuration is:

Intel NUC BOXNUC8i5BEH2

Samsung SSD 970 Evo M.2

Corsair Vengeance 32GB DDR4 SO-DIMM K2

I am not able to access the BIOS directly, only Visual BIOS (which has security boot settings, but nothing that reads as "TPM specific" - unlike other posts for this or similar problems).

Need a lifeline :)

Many thanks

1. If you will power ON your NUC with BIOS Security Jumper removed, it will boot into Configuration Menu. See page 41 and 42 in Technical Product Specification https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i3BE_NUC8i5BE_NUC8i7BE_TechProdSpec.pdf
2. Before you press on [3] in order to clear the TPM, please read the Warning in Table 28.

Hi Leon.

Many thanks for your instructions.

After removing the jumper and rebooting, and following the selection of option [3], upon subsequent reboot, I needed to then also select option [1] 'Suppress this menu until the BIOS Security Jumper is replaced.'

This allowed the box to reboot with the USB stick (19.04 specifically).

Once in, I started to back up files that were important.

But, then, mid-stream, death struck once again.

And, then the game repeated many times.

I re-inserted the jumper in the 1-2 position and, as expected, the same game continued.

Maybe I simply have a lemon NUC.

I will return it to the vendor and obtain a refund.

Many thanks for your help.

Hi Julian,

Sorry to hear that your problem wasn't solved. Did you disabled the Secure Boot in Bios Advanced > Boot section? If not, please do it.

Hi Leon.

Yes, I did.

But, to be sure, I repeated the process completely, unfortunately with the same results.

This box seems to be faulty, since I have not found reports of this problem persisting following these changes to the bios.

It looks like I will need to find another suitable home for my SSD cards.

Many thanks for your time all the same.
