drm/amdgpu: AMDGPU unusable since 6.12.1 and it looks like no one cares.

Dear Alex,

The situation is more than concerning and my frustration, as well as others, is growing.

There has been a hundred of reports on gitlab, I can find more on reddit, tech1level forum, phoronix forum, I got confirmation by some folks on Matrix that are staying in 6.1 and are starting to mock the amdgpu driver. I've seen features after features being merged in amdgpu yet people are laughing in forum, at how bugs are not fixed. On reddit, some users decided to go back on Windows because of it.

There has been 4 bisection attempts so far, that led to no result, and (I'm in part at fault here for having used an experimental filesystem with major version changes). There are people that managed to grasp debug infos before the timeout.

In two months, this significant issue will be a year old. 

I do not understand, how you guys are not hitting it/trying to bisect it. Are you not keeping your machine up for more than 30 sec.
With the immense spectrum of hardware concerned, I cannot believe that you guys are immune to this. And I cannot believe that you guys are letting this rot.

Right now, only a minority is managing to recover their session after a few minutes. Some people are able to get away with it by enabling the debug flag, but this only work for some people and there are no guarantees that it will last long. 

Please,
It's time to forget trying to pass the hotball and get a maintainer investigate and fix this before it gets too late. If we let it rot another year, no one will be able to bisect it because distros and hardware will make use of recent versions only.
