kernel splat

Not sure if the intel warn plays into things, since it happened from an interrupt. But it was interrupting a different process. Looks like the buffer already got unmapped somehow, or we're writing too far into it.

This is with a 4.3-rcN-ish nouveau module (despite the main kernel being 4.0).

Happened when running piglit in parallel (8 threads).
