Why this additional new line?
The intent is the devcoredump have different sections clearly
demarcated with an new line else "VRAM is lost due to GPU reset!"
seems part of the page fault information.
[gfxhub] Page fault observed
Faulty page starting at address: 0x0000000000000000
Protection fault status register: 0x301031
VRAM is lost due to GPU reset!
In that case I would print the newline independent if VRAM is lost or
not. Otherwise you get:
Protection fault status register:...
VRAM is lost due to GPU reset!
AMDGPU register dumps:
In one case and:
Protection fault status register:...
AMDGPU register dumps:
In the other case which breaks this sectioning quite a bit.

Apart from that looks really good to me.
