The /proc/vmcore is not present before or after the crash

I load the kernel from grub pass parameter: crashkernel=256M mem=2048M
and then kexec -p bzImage --append="root=/dev/sda5 maxcpus=1 irqpool
so i send request : echo c > /proc/sysrq-trigger

ok the kernel broken is loaded

Now i have a question:
The system is stopped and i receive the message:
Switching back to console

I assume that i need force reboot in this point, because system is freezed.

i dont see the /proc/vmcore , /dev/oldmem contains few datas

I miss some step?
