Ubuntu version:

Description:    Ubuntu 24.04.3 LTS
Release:        24.04
ii linux-firmware 20240318.git3b128b60-0ubuntu2.23 amd64 Firmware for Linux 
kernel drivers

Steps to reproduce: [brief summary from GitLab issue].

Kernels up to 6.14.11 boot normally.
From 6.15 up to 6.19-rc5, the system freezes during boot.
It appears that the MES initialization in this commit is not compatible with my 
hardware.
I tested with offending commit f81cd793119e7f4b426a825435d49cc10a081c7a 
reverted on kernel 6.15 and it tested OK with normal boot.
This should be fixed by 
https://github.com/torvalds/linux/commit/99579c55c3d6132a5236926652c0a72a526b809d

MES 0x51 is back from December 2023.  The latest upstream one is 0x82.

Solved by downloading this binary and swapping it out
https://gitlab.com/kernel-firmware/linux-firmware/-/blob/main/amdgpu/gc_11_0_4_mes_2.bin
Now MES feature version: bump up to 0x82.
