I tried changing the crashkernel value but nothing happened.
I got the information about the problem and I searched it and found that it might be due to graphic drivers.
But the problem is that I don't know which config settings are used for that.

Processor - AMD® Ryzen 5 1600 six-core processor × 12
Graphic card - GeForce GT 710/PCIe/SSE2

Hey,

This superuser post presents a solution, that might be helpful:

And as stated in this forum post, you can maybe find a bit more information
on your problem by disabling the `rhgb quiet` option.
