/sys/class/drm/card0/error output

While watching a movie using mpv I saw that the video got stuck for a while.
In dmesg I could see:

[497786.026819] [drm] stuck on bsd ring
[497786.028369] [drm] GPU HANG: ecode 1:0xeca7047e, in mpv/vo [12171], reason:
Ring hung, action: reset
[497786.028371] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[497786.028371] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[497786.028372] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[497786.028373] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[497786.028374] [drm] GPU crash dump saved to /sys/class/drm/card0/error

/sys/class/drm/card0/error output is attached.

In dmesg I also see a lot (really a lot) of this:

[465595.963234] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off
[465634.980054] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

[465695.018761] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

There is also another error in dmseg:
