      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.  Options used
     -v /usr/src/linux-2.4.24/vmlinux (specified)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.24/ (specified)
     -m /usr/src/linux-2.4.24/System.map (specified)
