Jul 16 01:54:09 pc kernel: The GPU crash dump is required to analyze GPU hangs, so please always attach it.
Jul 16 01:54:09 pc kernel: drm/i915 developers can then reassign to the right component if it's not a kernel issue.
Jul 16 01:54:09 pc kernel: Please see https://gitlab.freedesktop.org/drm/intel/-/wikis/How-to-file-i915-bugs for details.
Jul 16 01:54:09 pc kernel: Please file a _new_ bug report at https://gitlab.freedesktop.org/drm/intel/issues/new.
Jul 16 01:54:09 pc kernel: GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Jul 16 01:54:09 pc kernel: i915 0000:00:02.0: [drm] Resetting rcs0 for preemption time out
...Platform: Manjaro Linux 20.0.3 64 bit KDE, unstable branch (it has latest updates in Manjaro project).
Kernel: Listed in Manjaro Setting Manager (MSM): 5.8rc5.d0712.g11ba468-1. The same kernel listed in uname -r: 5.8.0-1-MANJARO.
Hardware briefly**: 1-year old mini-pc with the only GPU which is CPU on-die (on the same substrate as CPU is: Intel UHD Graphics 620). No any other GPU present in PC (ever).
Kernels affected looks like all current of the Manjaro Linux OS. The y are (at least):
4.19 LTS family and latest 4.19.132-1 LTS also,
5.4 LTS family (probably latest 5.4.51-1 also),
5.6 family (probably latest 5.6.19-2 also),
5.6-real-time family (probably latest 5.6.17_rt9-2 also),
5.7 family and latest 5.7.8-8 also,
5.8rc family and latest 5.8rc5 also.
Kernel. Usual behaviour:
4.19: restore state of graphics by resetting graphics (see 'More info by me also located on' link below),
5.7: hangs up but only picture (blinking picture with tens and hundreds colour rectangles in the black background), sound is playing back still, second terminal (Ctrl+Alt+F2) is available and working.
5.8rc (attention: not 'rt'): freezes completely OS: picture like still picture/photo, sound stops, no any terminals available: pc no responds. It is usually. Here that current ticket is then 5.8rc remaining 'alive' like 5.7 which is unusual and info gathered from second terminal session.
Additionally about kernels
Usually 5.8rc5 kernel freezes completely but in case of watching youtube video in opera web browser, paused, opened new tab with 'cs-online.club/en/servers' URL and press 'connect' btn on entry you want: connection stage starts and before game starts (before team selector) picture freezes and blinking with the center of the picture remainig as was (connection to server stage) and about 200px on each of 4 sides outside center rectagle picture is blinking with back color and (connection pictire + web browser tabs + taskbar) image. May be it is not always reproductable.
Very hard to catch 5.8rc5 kernel freeze cause usually OS freezes completely with static (not blinking) picture and second terminal session (Ctrl+Alt+F2) do not respond. The only way to reboot is to hold power btn on the PC case to power down PC via hardware method and then to click this power btn to start it again.
( More info by me also located on: https://forum.manjaro.org/t/random-freezing-with-resetting-rcs0-for-hang-on-rcs0/119313/34 )
Moreover: Manjaro Linux LiveCD v2003 (USB flash stick, was downloaded about 2 weeks ago) hangs on also during work as LiveCD. It has 5.6.15-1-MANJARO kernel built-in.
Features involved
looks like software-independent bug: software mentioned in "General steps to reproduce an issues" item below.
General steps to reproduce an issues
Based on randomly time and actions manner. Can't select the exact user behaviour, spontaneous error: it could be on logon screen before user input or after 12 hours of work. Usually after 30-120 minutes of very typical user actions in text editor, media player, web browser, desktop icons selection, selecting item in context menu on system tray icon, etc.
How often does the steps listed above trigger the issue
Issue occurred about 50-60 times for about last 2.5 weeks period. OS installation was 3-4 month ago and before that 2.5 weeks ago works well. May be software update was the cause of the problem, can't trace this now. Never saw such hard to catch bug and recently it became very very frequently several times per day at very least.
Display connector: (such as HDMI, DP, eDP, ...)
Monitor port: DVI-D.
PC port: HDMI (probably 1.4a).
Single cable (factory-made: without any adapters): one side has HDMI connector (PC) - other side has DVI-D connector (monitor).
Screenshot or photo (a picture is worth a thousand words)
see some of them by 'More info by me also located on' link to the manjaro forum (located above).
