[opensuse-factory] FYI: broken RDRAND and luks2 makes system unbootable

Reported here: https://bugzilla.opensuse.org/show_bug.cgi?id=1173022 Cryptsetup uses json-c to read data from luks2. Json-c on initialization reads some randomness, using RDRAND if present. It's not checking if RDRAND is working correctly, nor if "nordrand" kernel parameter is used. As a result it's just looping forever, making system unbootable.
