Kernel module ae4dma caused my system to not boot

[Jesper Dangaard Brouer <hawk@kernel.org>]

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:
