Sorry, I don't have an answer for you.

What chip do you have? I see

[    0.150863] smpboot: CPU0: AMD FX(tm)-9590 Eight-Core Processor (fam:
15, model: 02, stepping: 00)

(of course, I have the same board.) I don't have any page faults in dmesg
or on boot. In /etc/default/grub, I have
GRUB_CMDLINE_LINUX_DEFAULT="iommu=soft" (don't forget grub-mkconfig!).

I did have these kinds of errors earlier, but I don't remember what my
configuration was. I'm pretty sure it had something to do with iommu. Good
luck!
