Hello all, Why not load the following two modules?

[    6.997819] kmodloader: 2 modules could not be probed
[    7.001255] kmodloader: - padlock-aes - 0
[    7.004138] kmodloader: - padlock-sha - 0

If you try to load the modules on a CPU without padlock support (made by AMD or Intel), that message is expected. It's harmless.

On my VIA Nano CPU, the modules load just fine:
