No, it is quite a bit older.. And it should only go for TPM2, which I
don't think you have??
Maybe Jarkko has a guess, but sure sounds like something is recently

I'll come back to this. I have to re-read the whole mail thread to
get back into the context. Lots of multitasking because of release
and so forth. Sorry for the latency!
I started bisecting this issue. This is the current state.
```
