To: fedora-list@redhat.com, linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7BIT Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I compiled valnilla kernel 2.6.16.23 on 64bit Fedora Core 4 months ago. the kernels runs well for a lot of machines for months but weeks ago 4 machines dead with a black screen, we could ping them but failed to ssh into them. After power-cycled the 4 machines, I have found the following in the /var/log/messages. -- it looks that there were still enough free memory, though. Please help explain the output, and possibly what's the correct way to fix/workaround it. Thanks a lot.
