The big problem about this whole hardware bug is that to this day nobody was able to boil down the cause to a minimum example which necessarily means nobody knows how to completely avoid it. Without any way to guarantee the hardware bug is avoided no software at any level, be it kernel, OS or programs can be expected to even try avoiding it. That most existing owners didn't encounter it so far doesn't mean this will be true with all future software as well, so potentially everybody can be affected at some point. Of course you can pretend it will never affect you and I hope this works out well for you. But AMD at the very least needs to offer a software workaround that guarantees that the hardware bug is never triggered even in all the cases that currently make bug easy to trigger. If even that is not possible only an offer to exchange older chips is prudent.
