#80192 — Bug#1050602: linux: kernel 6.4.11-1 does not recognize TPM on lenovo 14IAU7 (Flex 7i)

Source: linux
Version: 6.4.11-1
Severity: important
X-Debbugs-Cc: justin.kinglacroix@gmail.com

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I use clevis-tpm2 to automatically unlock my harddisk on a 14IAU7 (Flex 7i),
and have been successfully using it for several months.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Update from linux-image-6.4.0-2-amd64 to linux-image-6.4.0-3-amd64

   * What was the outcome of this action?

Machine boots successfully, but TPM-based auto-unlock no longer works. In fact,
the following shows up in `dmesg`:

```

$
```

(Note the line that says "No TPM chip found".)

TPM-related stuff is also gone from /sys/kernel/security.

   * What outcome did you expect instead?

TPM continues to be recognized and used by linux.

Looks like this is an upstream bug that affects all Alder Lake (and maybe
newer) systems.

Thanks, I added that and also what appears to be the most current patch
submission which will hopefully fix that issue. 

The issue is also on Thorsten Leemhuis' radar:
https://lore.kernel.org/stable/fcf2f600-d1f0-de14-956b-4d4f3f0cb3fa@leemhuis.info/

It has been fixed in Linus' tree with 8f7f35e5aa6f2182eabcfa3abef4d898a48e9aa8
And a backport of that is currently available in the stable queue for 6.5, 6.4 
and 6.1, so it should make it into 6.5.3, 6.4.16 and 6.1.53 respectively.

Obviously, NEWS.Debian.gz is not an upstream file. :)
