The debug directory is not present, should I boot or compile with some particular option to enable it?
You need to compile with CONFIG_DEBUGFS and at runtime "mount -tdebugfs debug /sys/kernel/debug".
The /sys/kernel/debug/dri/0/i915_error_state will only be populated after a hang is detected.
OK, I had CONFIG_DEBUGFS but never mounted it. Unfortunately I rebooted since the problem, so now that file says: no error state collected
I'll get the contents when it happens again.
