Hi, I've been experiencing sporadic graphic corruption since a few stable kernel versions and I always thought "maybe is fixed in the next release", so I upgrade, but I usually experience a different problem then. This problems are exposed very rarely, maybe I have no problems like for a month or so.
Now I'm using kernel 2.6.39.1 and I experience one of this problem so I though it was time to report it. This is what I got in dmesg:

If you look in /sys/kernel/debug/dri/0/i915_error_state we can see what garbage the DDX [xf86-video-intel] fed the gpu.
cannot access /sys/kernel/debug/dri/0/i915_error_state: No such file or directory
The debug directory is not present, should I boot or compile with some particular option to enable it?
