Module ahci was missing. Added it to MODULES, remade the images, the problem remains. See also previous post: the same thing happens (but less frequently) when booting from the install media (USB stick). I must just have been lucky when I did the install. When there is the oops, none of the three modules you mentioned are in the list printed by the backtrace. Further action will have to wait until next year (this is at work). Until then, best wishes !
