Hi, thanks for your input.
>> Generally, it's not likely to be a fault of the IOMMU code and more likely a bug in the driver (not setting up DMA properly).
Ok, I CC'ed MPT driver list as well..
>> Really need to entire console output from boot. ACPI spews info about
the IOMMU resources that are relevant to debugging it.
I'm pasting it right here:

Maybe someone on MPTFusion list can answer that...?!

I couldn't tell that, is that supposed to be 'physical' address from the I/O device perspective, or the translated virtual address from the kernel point of view, or the host physical address.

Maybe but at this point I though the device tried to read from memory..

I think 4KB are reserved for each IOMMU.
Please note that interrupt remapping is disabled in BIOS.
