Do you have a test case that would show this up? I've been testing a centos-4 based server with the RH-derived 2.6.9-based kernel tweaked to disable 4K stacks and enable XFS and haven't run into any issues yet. This includes running the parallel IOR benchmark from 10 clients (and getting 200MiB/s throughput on reads). -- Joshua Baker-LePain Department of Biomedical Engineering Duke University - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
