If it's the ilk one we only know that 3.6.x series seems to be solid, and something in 3.7-rc (probably before -rc1) broke stuff.

Hm, then it could very well be something different, so I think we need to track this one as a separate bug. Can you please file a new one on bugs.freedesktop.org against DRI -> DRM (Intel) and attach dmesg when booting with drm.debug=0xe (just so we know what's in your box) plus the i915_error_state from debugfs once the gpu is hung (if you can get at that file, reboot kills it).
