Hi Basavaraj,
When rebasing my devel kernel to v6.14 (6.14.0-rc3-traits-009-bench+),
my AMD testlab system didn't boot due to the kernel module: ae4dma.
I disabled the kernel module via CONFIG_AMD_AE4DMA so I can boot my
system again.
CPU: AMD EPYC 9684X 96-Core Processor
As a help for you to debug here are the kernel console messages that
seems relevant:
