> Readers also suggested that if the amd64-microcode package were installed, it would fix the issue. This, too, is not the case; the amd64-microcode and intel-microcode packages are both installed by default on all Ubuntu 19.10 systems, including the one I'm experiencing the RDRAND failure on. I contacted AMD and asked representatives to check the status of that package and see if anything needs to (or can) be done about updating it.
Can anyone comment why the AMD microcode update doesn't seem to actually fix this bug? I've seen plenty of people commenting that you don't need a bios update and that it should, however the author seems to have tried that.
