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:
- Updated IDRAC & LLC.
- Updated BIOS.
- Tried NVRAM_CLR.
- 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?
