Reproducable: not really, so far it only happened to me while playing games. It happens rarely and without obvious triggering event.

$cat /sys/kernel/debug/dri/0/i915_error_state
no error state collected

What happens is quite simple, the whole system seems to be frozen, almost nothing reacts, certainly nothing that could help me to collect further information. The problem seems to be present since a while, it caused me to report this: https://bugs.freedesktop.org/show_bug.cgi?id=61411.
However, the first few times I played relatively demanding games and the laptop got rather warm, this time the game was far less demanding and the machine was not warmer than usual.

If there's any further information I can provide to help fix this,
please tell me.

These are the contents of /sys/kernel/debug/dri/0/i915_error_state after
the gpu hung event occurred.

Correction: I just realized that it's fine as long as I don't put
Chromium on the second display.  My statement "seemed to work fine
earlier this month" was actually due to that.
