ASUS  does not follow AMD microcode release in time, the latest motherboard
bios are using two month ago AMD
microcode.
Tried CPU's microcode with kernel, didn't work either.
fortunately, found a solution from arch linux comunity.  Appending nordrand
kernel parameter in grub resolved the issue.
Hope this can be documented some where to help others.
