The most simple solution may be to use serial console :-). You need a dummy (with cross TX/RX) serial cable connecting the box with your modified kernel as the 'debug end' and another Windows/Linux box as 'console'. Boot your kernel with parameter "console=ttyS0,115200" (or any speed your console support), and set your console properly ("remote terminal" on Windows or minicom on Linux), then you can see the kernel output on your console. Set the screen buffer of your console as big as you wish. :-) <div>2007/8/23, Feng Xian <<a href="mailto:feng.xian@gmail.com">feng.xian@gmail.com</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, I'm currently working on a project which needs to modify linux scheduler. But my new kernel always gets crashed after one-day's run. There is no OOPS message coming out when it crashed. What should I do?
