Wouldn't it be better to fix add_bootloader_randomness(), considering that
calls to that function are likely to happen quite early during kernel
initialization? Especially as it seems to have worked beforehand?

I have tried. I made wait_event_interruptible() optional, but then
crng_reseed() segfault badly. And I don't think crng_reseed() is
something that I could fix easily. Suggestions are welcomed ;-)

Regards,
Ivan
