GPU crash dump saved to /sys/class/drm/card0/error
I have a reproducible bug here. I'm on Arch/Linux, and I use chromium as a Web browser. If I visit https://www.android.com/versions/go-edition/ with it, the screen freezes for many seconds and dmesg gives me this message:
[drm] GPU HANG: ecode 5:0:0xfcefffdf, in chromium , reason: hang on rcs0, action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[drm] GPU crash dump saved to /sys/class/drm/card0/error
please include glxinfo output too

just a side note, I checked this issue on SNB, mesa-18.3.4 (built from git) and couldn't reproduce it. So looks like it is actual only on ILK
