Hi,
there is a subtle bug in 6.12 wrt TPM (in TPM, EFI, or perhaps in
something else):
https://bugzilla.suse.com/show_bug.cgi?id=1233752
Our testing (openQA) fails with 6.12:
https://openqa.opensuse.org/tests/4657304#step/trup_smoke/26
The last good is with 6.11.7:
https://openqa.opensuse.org/tests/4648526
In sum:
TPM is supposed to provide a key for decrypting the root partitition,
but fails for some reason.
It's extremely hard (so far) to reproduce outside of openQA (esp. when
trying custom kernels).
Mark "X".
Most of the 6.12 TPM stuff already ended in (good) 6.11.7. I tried to
revert:
423893fcbe7e tpm: Disable TPM on tpm2_create_primary() failure
from 6.12 but that still fails.
We are debugging this further, this is just so you know.
Or maybe you have some immediate ideas?
Nothing immediate but I've had to tweak quite a lot of TPM bus
integrity protection feature so it is a possibility that I've
made a mistake in a point or another.
Can you bisect the issue possibly?
No, see mark "X" :).
But follow the downstream bug for progress:
