You can test for this by setting the RSS parameter to 0 for the standalone module to enable multiple queues on the 2.2.9 driver. One other thing you might want to try would be to test the latest release candidate kernel from kernel.org. This would help to tell us if this is still an issue in the current kernel, or an issue that is present in just 2.6.33. Thanks, Alex
