He discovered that reducing the maximum transfer size issued to the adapter to 128KB stabilized his system. This is related to an earlier change for the 2.6.13 tree resulting from Martin Drab's testing where the transfer size was reduced from 4G to 256KB; we needed to go still further in scaling back the request size. Here is the patch that tames this regression.
