kexec not working

[Ronit Halder]

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
