I built a Debian package from the vanilla 2.6.33.2 and installed that on all nodes and tried my reproducer with the same results - nodes becoming unresponsive. I didn't try changing the tso and tx settings with the 2.6.33.2 kernel though. Let me know if that would be useful (and/or if there is another kernel that you would like me to test with) and I'll try to fit it in. Thanks again for your help. -stephen
