Hi Adrian,

I booted the same image using PXE and here is the serial output (just
pasting the last bit):








*....IOMMU: Create VTD context table for PCI bus 0xff
(pptr=0xffffff80a60de000)IOMMU 0x0: enabling... enabledIOMMU 0x1:
enabling... enabledStarting node #1 with APIC ID 1 Booting all finished,
dropped to user spaceReceived reserved IRQ: 124IOMMU: DMA read page fault
from bus/dev/fun 0xd0 on address 0x0:aae16000 with reason code
[email protected]:23 Could not find info*

Do you have suggestions for next steps? Do you perhaps have another CMA34CR
at Data61 so you can run the same test?

Regards
M
