	HN Discussion: ↑Confirms this fits a pattern of recurring RDRAND bugs on AMD Zen processors ↑Shares personal reproduction or corroborating evidence of the bug on their own hardware ~Downplays practical impact since hardware RNG output typically seeds a CSPRNG anyway ↑Recommends defensive practices like using XOFs to mitigate faulty hardware RNGs •Asks technical follow-up questions about scope and mechanism of the bug
