Hi, I am using 2.4.3 kernel and I am getting kernel panic. It doesn't happen very regularly so may be difficult to simulate. I connected my system to serial port and captured the log. Please suggest a way so that I can track down the problem. Will KGDB be of any help ? Please reply to me directly as I am not on the linux-kernel mailing list.
