4.19-rc3: IOMMU PT warnings: WARNING: CPU: 0 PID: 1 at mm/page_alloc.c:4065 __alloc_pages_slowpath+0xb7b/0xcd0

[Meelis Roos]

In 4.19-rc1, I found that to keep Intel integrated graphics working when 
VT-d is on, I need to have IOMMU passthough on or GPU init would fail 
with DMAR error and the screen would display static gibberish. So I 
turned IOMMU PT on by default in kernel config. It worked, also in rc2.

Now with rc3, it still works but I get some warning splats in dmesg 
about IOMMU passthrough:
