Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I have a Motorola Powerstack II Pro4000 that has PReP and OF and is not booting in 2.6. I hangs very early, the display stays in OF graphics mode and nothing is printed. So it does not reach vga_init in load_kernel, and I'm not sure it even reaches load_kernel. What is the best suggestion to debugging this? I have serial cable and could output chars there but what is the platform-specific code snippet that should output a char on serial port? -- Meelis Roos (mroos@linux.ee)
