Unrecoverable GPU hang with 5.4.0 kernel

Description

Hi,

I was using my system, doing nothing special, and the GPU hung.

There are many reports about GPU hangs but this one seems different:

• it occurred with kernel 5.4.0 instead of 5.3.x kernels (my Intel GPU also had many problems with 5.3.x kernels)
  
• the GPU never recovered (which BTW caused some data loss). I had to ssh into the system to get debug info.
  

Here is some system info (full details below):
