[kbl] GPU hangs when using Blender 2.83

• A clear subject describing the issue.

  • Blender 2.83 causes GPU to hang under almost any circumstances whether it's just moving objects in solid view or previewing complex shaders with both Eevee/Cycles
    Does not appear in blender 2.82 and prior

• Steps to reproduce the issue.

  1. Get an Intel UHD 620 GPU
  2. Do anything in blender 2.83

• How often does the steps listed above trigger the issue? For example: always, 1 out 3 times.

  • Always, in a matter of minutes or even seconds

• Which platforms and features are affected (if you can).

  • Intel i5 8250u with UHD 620 graphics
    Both iris and i965 MESA drivers

• The following information about your system:

  • -- system architecture: x86_64
  • -- kernel version: 5.8.0-rc5logo (basically a stock kernel with FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER=y)
    But the problem persists on: 5.6.7, 5.7.0, and debian's stock 5.7.0-1
  • -- Linux distribution: Debian Testing
  • -- Machine or mother board model: Lenovo ThinkPad T480s (20L7001VRT)
  • -- Display connector: eDP
