[Bug 105733] Amdgpu randomly hangs and only ssh works. Mouse cursor moves sometimes but does nothing. Keyboard stops working.

Tried getting all binaries available here
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu
.

Even that I included the polaris binaries in the kernel, some binaries were
missing (exactly those that were required...).

I've seen that before, but since sometimes it got working I just thought that
some other bin was being used instead.

Well... I launched Unigine Valley as a test and now the problem is even worse :

[From dmesg]
```

```

The symptoms and reactions are the same as above. I got the output from a ssh
because only the cursor was moving and nothing else working.

So ... did my card die or is it a bug?

By the way ... I also have an RX580 and the problem described firstly was
happening too. (I had not tried forcing binaries before)
