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.
