boot fail after linux kernel upgrade

Hi, i have struggled with the below issue

My system is  POWEREDGE R7525, running with Ubuntu 20.04.2 LTS.

I attempted to build and install Linux kernel version 6.4 for the purpose of making kernel modifications. However, the system encountered the following error and failed to boot:

(before BIOS update)

I've attempted the following:

1. Updated IDRAC & LLC.
2. Updated BIOS.
3. Tried NVRAM_CLR.
4. Try another version(kernel 6.2, kernel 5.13 ... )

When I installed Ubuntu installation, the kernel version was 5.15.0.56, and there were no issues with that kernel.

(after)

Could anyone help me, please?
