And with net-next we might even be able to get past that magic limit? net-next is linus-latest plus the latest and greatest networking bits: $ cat .git/config [remote "net-next"] url = git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6.git fetch = +refs/heads/*:refs/remotes/net-next/* ... so might be worth a test. Just to satisfy our curiosity and to possibly close the entry :-) Ingo From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ingo Molnar Subject: Re: [Bug #11308] tbench regression on each kernel release from 2.6.22 -> 2.6.28 Date: Fri, 21 Nov 2008 09:30:44 +0100 Message-ID: <20081121083044.GL16242@elte.hu> References: <1ScKicKnTUE.A.VxH.DIHIJB@chimera> <20081117090648.GG28786@elte.hu> Mime-Version: 1.0 Return-path: Content-Disposition: inline In-Reply-To: Sender: kernel-testers-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-ID: Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Christoph Lameter Cc: "Rafael J.
