Ah, thankyou. I shall give this a try on tuesday when I am
physically back in front of the machine. I have been trying without
the oath as you asked by the way, and with the latest microcode
update (0x8001137) it also seems stable, without these tweaks. But I
havent stressed it too much - if the errata says to set the bits then
we should set the bits.

I was wndeting about that - but I dont have a Ryzen 2 to hand to test
with unfortunately.

Will let you know how the patch goes next week, thanks,
