Message-ID: <20120601155447.GG3671@sgi.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.20 (2009-06-14) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I just tried to boot an 8TB system. It fails very early in boot with: Kernel panic - not syncing: Cannot find space for the kernel page tables A git bisect lead me to commit 722bc6b16771ed80871e1fd81c86d3627dda2ac8. A git revert of that commit based on Linus' current as of a few hours ago (commit fb21aff) does boot past that point on the 8TB configuration. Thanks, Robin
