Hi Rami, kexec -p executes normally. Then when I do echo c > /proc/sysrq-trigger, screen freezes and nothing happens. But, There is a small thing which is different when I execute echo c > /proc/sysrq-trigger without kexec -p, the caps lock light blinks. But in case of kexec -p ... and cho c > /proc/sysrq-trigger, the caps lock doesn't blink. Some time screen messes up. regards, Ronit On Sat, Mar 5, 2016 at 11:01 PM, Rami Rosen <roszenrami@gmail.com> wrote:
Hi Ronit, Can you please tell what happens when you ran the "kexec -p" that you mentioned ? Do you see any message on screen ? Does it hang immediately ? Regards, Rami Rosen

When I am doing normal load of kernel using kexec, it works.
#kexec -l /boot/vmlinuz-4.3.0-crash+ --initrd=/boot/initramfs-4.3.0-crash+.img --append="root=/dev/mapper/fedora-root 1 irqpoll maxcpus=1 reset_devices"
#kexec -e
But, when I am doing load on panic using kexec, it isn't working.
#kexec -p /boot/vmlinuz-4.3.0-crash+ --initrd=/boot/initramfs-4.3.0-crash+.img --append="root=/dev/mapper/fedora-root 1 irqpoll maxcpus=1 reset_devices"
#echo "1" >/proc/sys/kernel/sysrq
#echo c > /proc/sysrq-trigger
What am I doing wrong?
