Hello Jens,
Thanks for help. I just applied the patch. Unfortunately it doesn't work.
Can you try and additionally boot with iommu=off as a boot parameter?
Yes. This is the end of getting any sata devices. See screenshots for
errors. It continued untill ata4. At the end no root device was found.
Hmm, even though the address is set to 0xffffffff we still seem to
receive requests outside that range. Lets assume it's the scsi logic,
can you test this? IOW, patch + iommu=off + this patch.
I probably wont see any more mails tonight, we can continue this
tomorrow (or someone else can step in, whatever comes first :-)

I applied the path. Got Hunk #1 succeeded at 1562 with fuzz 2 (offset
-10 lines).
I didn't compile completly.
