    Discussion has moved to v2 patch https://lore.kernel.org/lkml/20251018024010.4112396-1-gourry@gourry.net/ https://lore.kernel.org/lkml/20251018024010.4112396-1-gourry... > No it doesn't [affect RDRAND], AFAIK. The only one affected is the 32-bit or 16-bit dest operand version of RDSEED. Again, AFAIK.

  RDSEED and RDRAND always seem to be causing issues heh.
