Happened to me too on an XPS 13 9360 kabylake:

Sep  3 22:02:20 debian kernel: [185417.238668] [drm] GPU HANG: ecode
9:0:0xfffffffe, in gnome-shell [1226], reason: Hang on render ring, action:
reset
Sep  3 22:02:20 debian kernel: [185417.238672] [drm] GPU hangs can indicate a
bug anywhere in the entire gfx stack, including userspace.
Sep  3 22:02:20 debian kernel: [185417.238673] [drm] Please file a _new_ bug
report on bugs.freedesktop.org against DRI -> DRM/Intel
Sep  3 22:02:20 debian kernel: [185417.238675] [drm] drm/i915 developers can
then reassign to the right component if it's not a kernel issue.
Sep  3 22:02:20 debian kernel: [185417.238676] [drm] The gpu crash dump is
required to analyze gpu hangs, so please always attach it.
Sep  3 22:02:20 debian kernel: [185417.238678] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Sep  3 22:02:20 debian kernel: [185417.238779] drm/i915: Resetting chip after
gpu hang
Sep  3 22:02:20 debian kernel: [185417.238850] [drm] RC6 on
Sep  3 22:02:20 debian kernel: [185417.258102] [drm] GuC firmware load skipped

Unfortunately I could not save /sys/class/drm/card0/error as this resulted in a
kernel panic.
