Description Michael Tremer 2018-09-07 13:10:41 UTC 
RDRAND isn't listed as a source and therefore rngd doesn't start.

The configure script of rng-tools checks the following:

> AM_CONDITIONAL([RDRAND], [test $target_cpu = x86_64 -o $target_cpu = i686])
> AS_IF([test $target_cpu = x86_64 -o $target_cpu = i686], [AC_DEFINE([HAVE_RDRAND],1,[Enable RDRAND])],[])

Since we are i586, support for RDRAND is disabled.

I will send a patch shortly.

This was a problem in rng-tools.
Comment 5 Michael Tremer 2018-09-10 15:27:24 UTC 
Unfortunately the maintainer of rng-tools has rejected the patch because he does not understand that i586 is compatible with modern processors.

That means that we will have to carry this patch ourselves.
