I will do so.

FYI, when I came back to this test box just now (after leaving it
since yesterday) and now it is completely broken:

[89210.340696] DMA: Out of SW-IOMMU space for 1600 bytes at device 0000:03:00.0
[89210.449936] tg3 0000:03:00.0: swiotlb buffer is full (sz: 1600 bytes)

The root fs block device is also unuseable and gives lots of EIO.

This is with 3.14.21, baremetal, with `iommu=soft swiotlb=force'.

Ian.
