We can't go back and fix the old 2.6.9 kernel, sorry (and odds are you aren't testing a kernel.org 2.6.9 kernel release either, right?) Can you please test the 2.6.17 kernel or newer from kernel.org with this test? That way we can try to fix the issue if there still is one. thanks, greg k-h ------------------------------------------------------------------------- Using Tomcat but need to do more?
