Darn, I meant to have it display the output of the tool.

Can you just run this from the command line:
<load drm with debug=0x6>
<load i915>
sudo dmesg -c > /dev/null
sudo <igt_dir>/tools/intel_l3_parity 0,0,0
sudo <igt_dir>/tools/intel_l3_parity

Paste the everything on the command line for the above, and attach the dmesg
afterwards, please.

Thanks.
