Not sure how I can really reproduce this bug as one build worked fine
within my last v3.8-rc1 kernel.
I increased the parallel-make-jobs-number from "4" to "8" to stress a
bit harder.
Just building right now... and will report.

If you have any test-case (script or whatever), please let me/us know.

Thanks.
