McGrew" To: Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org So I'm trying to build a new special kernel and of course, as Murphy says, it'll blow up the first 1,000 times! I need to capture the boot messages because I'm getting a lot of errors scrolling by before the kernel panics and I'm toast and have to revert back to my old kernel. Once I revert back to my old kernel, all my previous messages are lost and dmesg does me no good! How can I make the kernel output to a file or some other means as soon as it starts loading so I can capture this stuff? TIA, -brian Brian D.
