To everyone testing on Intel chipsets, make sure to also test with either LibreOffice or PyCharm/JetBrains IDE and manipulate (resize/move/type in the UI) to attempt to trigger the i915 VMA/list corruption bugs.
@jforbes, I hit it immediately trying your kernel build with 5.5.2 from Koji installed manually. I was one of the first reporters too: https://gitlab.freedesktop.org/drm/intel/issues/1179
Dell Precision 5540 (Coffeelake)
5.5.x are missing critical patches in drm/i915 which render Intel systems unusable (hanging X) with all 5.5 kernels. The patches into 5.5.x are pending but are not there yet.

This build fixed Intel AX200 iwlwifi firmware crashing bug: https://bugzilla.redhat.com/show_bug.cgi?id=1738361
Intel AX200 WiFi 6 does not work with 5.2.x kernels due to firmware version mismatch.
