I don't mind Intel keeping very quiet about fixed-in-microcode bugs that don't directly affect valid userspace programs, like « Instruction Fetch May Cause Machine Check if Page Size and Memory Type Was Changed Without Invalidation » or « Execution of VAESIMC or VAESKEYGENASSIST With An Illegal Value for VEX.vvvv May Produce a #NM Exception » but something like this should be announced clearly. (I keep my microcode packages up to date, but I don't normally bother rebooting when an update comes in.)
