kernel. following are the commands am using. Can some one point, if there is any thing wrong with this. chkconfig kdump on /etc/init.d/kdump start kexec -l --append="`cat /proc/cmdline`" --initrd=/boot/initrd.img-2.6.35.10-kdump /boot/vmlinuz-2.6.35.10-kdump kexec -e works fine and loads the kernel successfully, i will be able to see starting new kernel in the shell chkconfig kdump on /etc/init.d/kdump start kexec -p --append="`cat /proc/cmdline`" --initrd=/boot/initrd.img-2.6.35.10 -kdump /boot/vmlinuz-2.6.35.10 -kdump i simulate the panic by using echo 1 > /proc/sys/kernel/sysrq echo c > /proc/sysrq-trigger which just crash the kernel and system hangs, and it does not show any message starting new kernel. does /var/crash or kdump target directory as mentioned in /etc/kdump.conf exists? sometime it may be a while before it starts to dump if memory on machine is huge and you have set kdump level to dump everything.
thx,thayumanavar s.
