I'm not likely to be much help on VT-d issues, but maybe it
would be useful to dump all the values in the BUG_ON if its
going to trigger, ie just before

BUG_ON(addr_width < BITS_PER_LONG && (iov_pfn + nr_pages - 1)
>> addr_width);


if (addr_width < BITS_PER_LONG && (iov_pfn + nr_pages - 1) >> addr_width)
pr_err("VT-d BUG! addr_width %d < %d (iov_pfn 0x%lx
nr_pages %ld)\n", addr_width, BITS_PER_LONG, iov_pfn, nr_pages);

and report what that prints.

- R.
