I've downloaded and patched the 3.7.10 tarball and still get the same
output I got before; different output from yours. I'm not sure the
patch is complete or applying correctly, are you?
Could you please check whether the patch you're applying is the same
as the attached file?

I think some important error messages might have been lost here.

You captured a complete dmesg at
https://home.comcast.net/~jpiszcz/20121128/dmesg.txt
with iommu on. Are you still able to get the same with 3.7.10 if you
exclude this patch, or has something else changed?

a.
