[2020.08.07] i915 GPU hang report on 5.8.0-1-MANJARO kernel

This is another one case of GPU hang on the same PC (HW + Linux distro). It is my ongoing 1.5-month long rally of PC freezes and GPU hangs.

Since prev. report #2305 (closed) got these packages updates:

grep --text -iE 'installed|upgraded' '/var/log/pacman.log' | tail -n 50

The next issue: #2307 (closed)

My PC experienced about >100 times of (PC freezes + GPU hangs) during last 6 weeks on every kernel 'family' (4.19, 5.4, 5.7, 5.8-rc) avail. in the distro. 4.19 looks like more stable and usually (but far away from always) able to reset GPU and to continue to work without the PC reboot. The more modern kernel version the much faster GPU hangs without any software reset (which 4.19 kernel can do) or PC freezes.

PC freeze or GPU hang usually happens while semi-transparent, fade in/out, blur effects is/are in action.

I have a feeling that fast occurred serie of GPU hangs leads PC to freeze. If only one-two GPU hang happened 'at once' than PC may freeze or may not freeze.

Steps to reproduce the issue in this ticket

After OS was loaded I entered user session. I started to move desktop icons to random positions. Moving by 1 icon or by selected groups. made about 40 times of meaningless movements. After than I pressed Ctrl+Alt+Del semi-transparent menu just start to show, freezes for several seconds and picture changes to 3 images on a monitor: fully black background --(after 0.6-0.8 sec)--> 1/4 of screen was filled with relatively low size color rectangles --(another 0.6-0.8 delay)--> full screen of that rectangles (see not-in-focus-photo below). And that 3 images exchanging in infinite cycle. By pressing my hotkey I was able to execute the script to collect the error data. Pictures on monitor was in that cycle until black screen of PC reboot via software (it is the last line in the script).

How often does the steps listed above trigger the issue

Frequency of the PC freeze or GPU hang are near highest possible. It could happen on logon screen without any user activity or during GUI session actions: on a first or 5th or 40th minute. Average is about 1-2 minutes. It is not a concrete exact action, it is general unexpected case and it did happen in (m)any types of typical user activity such as:

-) on logon screen (without any user action, even mouse touch; saw that for about 2-3 times),

-) moving desktop icons,

-) open start menu,

-) open context menu,

-) moving cursor in the text editor via keyboard navigation keys,

-) surfing in system settings window,

-) typing text in terminal emulator (GUI),

-) installing updates in GUI app or GUI terminal emulator,

-) open or surfing in Opera web browser: list of gitlab commits viewing, watching youtube videos (not fullscreen and not even touch keyboard and mice at least for about last 1-2 minutes), extremely fast freeze/crash while surfing maps.google.com, maps.ya.ru,

etc.
