"Worrying number of hardware/BIOS bugs" == "hardware is very buggy, so there
might be some other hard-to-discover bugs which might affect us"

BUT

I just noticed that some driver is leaking IOMMU space (which is used both by
nouveau and your SATA controller), so maybe enabling CONFIG_IOMMU_LEAK in
kernel config will help figure it out.

Why do you have iommu=force in kernel command line?
Did you enable IOMMU in BIOS?
