No, this *is* the way to keep the conversation sane, without veering
off into some absurd claims.
So, to cut to the chase: you can simply add "rdrand=force" to your
cmdline parameters and get back to using RDRAND.
And yet if you still feel this fix does not meet your expectations,
you were told already to either produce patches or who to contact. I'm
afraid complaining on this thread won't get you anywhere but that's your
call.
