hello Sanjay, > > suppose your new compiled kernel source is in > /home/guest/linux > To debug the oops messages > dmesg | ksymoops -m /home/guest/linux/System.map -v /home/guest/linux/vmlinux but does that require me to boot the same new kernel. cause when i boot new kernel and get oops with it. i have only option to boot my default kernel and check oops message. so in that situation does above work? cause i run above command and get [root@src root]# dmesg | ksymoops -m /usr/src/linux-2.4.24/System.map -v /usr/src/linux-2.4.24/vmlinux -o /lib/modules/2.4.24/ ksymoops 2.3.5 on i686 2.4.20-8.
