GPU crash dump saved to /sys/class/drm/card0/error

When trying to debug why my desktop will freeze when resuming from a suspend
(freshly installed Fedora 25 KDE, i3-4150), I tried following through
https://01.org/blogs/rzhang/2015/best-practice-debug-linux-suspend/hibernate-issues
and running "echo freeze > /sys/power/state" as root. This suspended my
computer, but this time, instead of freezing completely, after a few seconds I
could use the computer again, and got this in dmesg output:

[ 2413.798896] [drm] GPU HANG: ecode 7:0:0x87d5bef8, in kwin_x11 [1164],
reason: Hang on render ring, action: reset
[ 2413.798898] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2413.798899] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2413.798900] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2413.798901] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 2413.798902] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 2413.798970] drm/i915: Resetting chip after gpu hang

I'm attaching the crash dump as described.
