In private correspondence with Prashant we have established that Prashant was using a different kernel configuration. Prashant provided me with their kernel and module binaries, which work in my environment. I have also established that I can reproduce the problem with 3.14.37 (`iommu=soft swiotlb=force' baremetal => all rx wholly corrupted). The kernel config I was using is here: http://logs.test-lab.xenproject.org/osstest/logs/50387/build-i386-pvops/build/config As far as I am aware no-one at Broadcom has attempted a build and test using my kernel config. Thanks, Ian.
