OK, I'm having another i915 "episode" and now I have the debugfs
mounted. Here is the contents of
/sys/kernel/debug/dri/0/i915_error_state:
http://llucax.com.ar/tmp/i915_error_state.txt (1.4MiB)

Here is the error message shown in dmesg:

[1259708.264742] Out of memory: Kill process 16640 (firefox-bin) score 504 or sacrifice child

Any ideas? Thanks!
