After less than a day, it failed. Unfortunately I forgot that the crash dump
needs to be saved from /sys/class/drm/card0/error and rebooted the machine. I
will try to catch it one more time and save a dump. Here's the kernel log:

May  2 15:21:48 sb kernel: [63357.870540] [drm] stuck on render ring
May  2 15:21:48 sb kernel: [63357.870548] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
May  2 15:21:48 sb kernel: [63357.870552] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
May  2 15:21:48 sb kernel: [63357.870554] [drm] Please file a _new_ bug report
on bugs.freedesktop.org against DRI -> DRM/Intel
May  2 15:21:48 sb kernel: [63357.870556] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
May  2 15:21:48 sb kernel: [63357.870559] [drm] The gpu crash dump is required
to analyze gpu hangs, so please always attach it.
