Dear Stephan,


Thank you for the quick response.

Building CRYPTO_RSA not as module, but into the Linux kernel,
`rsa_init()` takes 130 ms on an ASRock E350M1.

(Timings are shown by adding `initcall_debug` to Linux command line [1].
The times are visualized by `analyze_boot.py` from pm-graph [2] or
`systemd-bootchart`.)

This is quite a lot of time compared to other modules, and I wonder if
there are ways to decrease that time other than building it as a module,
and not signing modules?

Is the testmgr compiled? If yes, the self test may take that time.

It looks like it is, as the tests are not disabled.

```
$ grep MANAGER_DISABLE_TESTS .config
# CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
```

I’ll try an image without the tests, and will report back.


Kind regards,

Paul
