end Kernel panic – not syncing : System is deadlock on memory

At the time of reboot after new kernel compilation
I got error

please provide solution.

I expected for reboot with new kernel module in ubuntu 20.04

>Solution :

I faced this same issue in virtual box when I was doing new kernel compilation and reboot.

In my case ram given to virtual box was 2GB ,so I increased it to 5GB in virtual box
from setting==>system==>base memory .
After rebooting again.
It works properly.
hope it works.
