I started to see the same GPU HANG error sometime this year (2020).
I am using the default "modesetting" driver with automatic configuration
and no "xorg.conf" file (/etc/X11/xorg.conf). The Xorg log file
(/var/log/Xorg.1.log) is attached.
The following error occurred on April 1, 2020, at 18:36:30.
[drm] GPU HANG: ecode 9:0:0x85dffffa, in Xorg [1784],
reason: Hang on rcs0, action: reset
i915 0000:00:02.0: Resetting rcs0 after gpu hang
[drm:gen8_reset_engines [i915]] *ERROR* rcs0: reset request timeout
i915 0000:00:02.0: Resetting chip after gpu hang
[drm:gen8_reset_engines [i915]] *ERROR* rcs0: reset request timeout
[drm:i915_reset [i915]] *ERROR* Failed to reset chip: -5
[drm] Reducing the compressed framebuffer size.
This may lead to less power savings than a non-reduced-size.
Try to increase stolen memory size if available in BIOS.
The next error occurred on April 4, 2020 at 12:15:13.

I have now switched to the older "intel" driver to see whether that
might solve the problem, using the following "xorg.conf" file:
# Try "intel" instead of "modesetting" driver to fix GPU HANG.
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
# Disables acceleration
# Option "NoAccel" "True"
# Disables only 3D acceleration (Direct Rendering Infrastructure)
# Option "DRI" "False"
EndSection
My system information is listed below (now showing the "intel" graphics
driver).
