I have run a few tests on the original code and the patches posted to the list, and have some interesting results. First, my system setup: Dual Opteron, 8GB RAM, SIL SATA controller (which is apparently 32bit), pcnet32 NIC (compiled as a module) connected to the network. The latter 2 should show any bounce buffer problems.

We don't care about AMD systems for this problem because they don't use swiotlb in normal operations, but the AGP remapping hardware (except on one particulr chipset, but people don't build servers from that)
If anything then testing results from Summit3 based Intel x86 NUMA systems would be interesting.
